The 2021 ATC Projections have arrived at FanGraphs!

The Average Total Cost projection system (ATC) gets its name from the fact that it “averages” many other projection systems together. ATC also happens to be my initials.

ATC is a “smart” projection aggregation model. While most other aggregation systems typically apply equal weight to all underlying data sources, ATC assigns weights based on historical performance. The method is similar to what Nate Silver does with his political forecasting at www.fivethirtyeight.com. Read more about how ATC works in last year’s introductory ATC article.

ATC’s advanced methods have paid off. Last year, FantasyPros ranked ATC as the most accurate baseball projections, even more accurate than their own. Annually, I conduct my own projections review using a game theory method, which has consistently shown that ATC has outperformed other projections. You can read the results of last year’s study here.

Starting this year, ATC will include three new volatility metrics to be described later in this article. Aside from introducing the concepts behind these new metrics, we will also discuss how a fantasy manager might use them in practice.

First, let’s quickly remind everyone on where to find the ATC projections at FanGraphs.

Viewing ATC

There are currently three ways to view and utilize the ATC projections on the site.

Many thanks to Derek Carty of RotoGrinders for his assistance on this article, and for his player notes on a few 2020 player projections.

In my previous article, 2020 Projection Systems Comparison – A Game Theory Approach, I compared several excellent projection systems in terms of fantasy baseball profitability for 2020. It was not the typical statistical comparison, rather – I used a game theory approach. This was the third such annual article that I had put forth in evaluating projection systems.

Earlier this year, Derek Carty unveiled a new version of his already excellent THE BAT projection system. The new system is called, THE BAT X. The major innovation of THE BAT X is that it incorporates Statcast data into the fold. You can read more about THE BAT X works in Carty’s introductory article found here on the pages of FanGraphs.

I have typically evaluated THE BAT within my 2020 Projections comparison. With this season (despite the short duration) as the inaugural run of THE BAT X – Derek asked me to take a deeper look into how his new projection system had performed. To do this, I went back and revisited the same game theory methodology applied to THE BAT X. The initial results look very promising for the young system.

In this article, I will go through what had changed between THE BAT and THE BAT X as far as the game theory simulations. For a few of the largest and most impactful player performance differences, I will also include some analysis from Derek Carty himself as to why THE BAT X made those adjustments.

Introduction

Back in 2018, I introduced a game theory approach for comparing baseball projection systems. Proudly, the article was nominated for Baseball Article of the Year by the Fantasy Sports Writers Association (FSWA). The game theory methodology is now back for its third straight year.

This approach is not the standard projections comparison analysis that most others embark on. The typical comparison makes use of some type of statistical measure. The standard analysis involves calculating least square errors, performing chi-squared tests, or perhaps even hypothesis testing. My method does not use any of these capable methods.

Introduction

Previously, I looked at the largest auction player bargains of 2020. These were the players who were highly profitable after considering their opportunity cost of acquisition. Value should always be considered relative to cost.

We defined the bargain amount as:

$Bargain = $Value – $AAV

We defined $Value as the accumulated 5×5 full season rotisserie value of each player, and $AAV as the average auction cost to purchase the player pre-season. We made use of the July NFBC Average Auction Values, which was one of the best sources of “market” data this year.

Whereas I previously looked at the players who generated the most excess value in 2020, today’s attention will be directed to what I refer to as the value drainers. These are the largest “rip-offs” of the season – i.e., the players who earned the most negative profits for fantasy owners on a full season basis (net of their auction price).

Prior to unveiling 2020’s most unprofitable players, it is important to discuss one additional step in the analysis – the capping of values. I have previously spoken about this concept, but I will touch on it again today.

Eduardo Rodriguez was a player that I drafted on a few of my fantasy rosters this season. His NFBC average auction value during July drafts (auctions) was $7. In Tout Wars, I acquired the Boston pitcher for $10. Unfortunately, Rodriguez came down with COVID-19. He developed heart complications due to the virus, and consequently did not pitch a single inning in 2020.

The question is – what value did Rodriguez accumulate in 2020? What damage did he cost to your team’s aggregate value? Owners certainly lost their original investment on him, but how much more were they penalized? He wouldn’t have made it to one’s active roster – but how much did it cost owners for Eduardo taking up a bench spot?

Introduction

The key to succeeding in fantasy baseball:

Maximize the value of your accumulated roster.

At the start of a draft, each fantasy owner is handed a set of draft picks. Each owner receives a 1^st round selection, a 2^nd round selection, a 3^rd round selection, and so on. If your league chooses to hold an auction rather than a more traditional serpentine draft – each team is handed $260 at the auction start. Players are then purchased throughout the auction with the use of these finite funds.

The key to gainfully drafting is not to draft a 3^rd round player in the 3^rd round, or a 9^th round player in the 9^th round, etc. The key is to draft a 3^rd round player in the 10^th round, and a 9^th round player in the 20^th round.

In an auction, if you purchase every player at his projected value, you will have paid $260 of auction dollars for $260 of value. What you will have is an average team. You won’t finish last, but you won’t finish first. Instead, with your $260 – you need to buy some $290 or $300 or $310+ of total value.

The key is to make a “profit” on as many roster spots as you can. The goal is to purchase players at bargain prices.

I have asked this question before – but it is worth asking every now and again. Suppose that you competed in an NFBC fantasy baseball auction back in July this season.

Which player was the better purchase?

Bryce Harper (OF, PHI)

OR

Andrew McCutchen (OF, PHI)

Before opining on the better Philly outfield purchase of 2020, let’s take a look at their final 2020 stat lines:

On the surface, it seems like a pretty obvious answer. Harper had more HR, SB, R and a better batting average than McCutchen. He had just one fewer RBI.

The 2020 MLB regular season has now concluded. In most years, this introductory sentence would be a simple fact. One ordinarily would not pay much attention to such an evident truth. However, in 2020, the consequence of baseball completing the year without a major full stop is a sparkling achievement.

Yes, the Marlins and Cardinals did not play for the course of about a week due to team COVID infections. Yes, there were more make-up doubleheaders played in 2020 than in any season during my lifetime. Yes, there were a few teams that made the playoffs despite a losing record. Yes, the league-wide batting average of .245 was the 6^th lowest full-season mark since 1900.

But baseball made it through, and now embarks on their expanded playoffs journey.

As such, it is now time to check back on how we fared in the fantasy season. For me personally, it was a rather positive one. I did not finish below 6^th place in any league that I played in this year. Amazingly, I was crowned as the 2020 Tout Wars Head to Head League Champion, my very first expert league title. 2020 showed that the ATC projections work well, even in smaller sample sizes.

In today’s article, I will recap my 2020 bold predictions. To remind the reader, the goal at the outset was to predict 70^th to 90^th percentile events (10% to 30% likely occurrences). I don’t expect to get the majority of these correct. If I wanted to achieve a higher success rate, I would simply have predicted that Jacob deGrom would win the Cy Young award, and the like.

Now let’s recap! Read the rest of this entry »
