And yet I still search for the reason that Joey Meyer failed to make an impact…

Haha, awesome. Great to have one thing to rule out as a consideration.

Is this true? or is the answer “We don’t know”?

Has the statute of limitations passed on stealing old Deadspin jokes? I’ve been waiting to start my Bear Fridays twitter feed

Did large boned first basemen descend from the robust Australopithecines whereas the smaller, thinner middle infielders are the scions of the gracile species like afarensis?

You should test your hypothesis and let us know how it goes.

It’s kind of hard when weights listed for players, especially “big-boned” players, bear little relation to reality. If you had accurate weights, you could design a good study.

Is anyone else seeing the article text show up in Spanish instead of English?

Thank-you Jeff, for such a succinct article! 😉

So I guess Jeff gets paid by the article, not by the word.

“From all these parallel lines, you can see it indisputably! Pablo Sandoval was younger than Dexter Fowler at the start of last season, and as hard as it is to believe, he’s still younger than Dexter Fowler now!”

This is exactly why I just got a membership. Take me away from the logic spinning world and into a world of baseball logic and nonsense. More must read articles Jeff!

Still, there are those players whose FEMUR always seems to outperform their xFEMUR no matter what.
