A first-round pick every several years that's a pitcher doesn't invalidate the concept that they predominately pump resources into the position side. This has been well-established with the Sox organization for some time. They love and draft up the middle athletes. Yes, they take a Tanner Houck here and there and not pass up on a Jay Groome when he falls. But those are more of an exception than a rule.
If you purely look at the numbers, it's not going to be lopsided. You have a 180-man roster to fill out across the minors and you need roughly half pitchers at every level. But if you look at where the money is predominately being spent over the long term, it's hitting. It's much more hitting. And the fact that they draft a Trey Ball, or Jay Groome high here and there and they flop only strengthens the argument that they also develop position players better. That and you hit on position players much more often, thus increasing the probability of a dud draft when going all pitching.
