If there's one guy you can't hang this on, it's Boone. I kind of agree with A-Rod in that regard. He didn't assemble a team with 5 DHs, 3 LH catchers, extremely limited flexibility and wildly inconsistent defense.
If you look at Yankee's players, there's very few well-rounded players, but many that do 1 thing really f***ing well, and get exposed when their weakness is targeted.
That's not to say the Jays don't have those types either, there's just fewer of them, and the skillsets of the rest of the roster cover them up incredibly well.
