I read your post and got your point. I just think it's nonsense, and you apparently have reading comprehension problems.
Let me put it in simpler terms: They will help the lineup, but the impact will likely not be as big as you're making it out to be because of holes in other positions, other players regressing, and the regression Tex and Youkilis are suffering themselves.
If the Yankees are middle of the pack in OPS right now, Tex and Youk won't move them from there, even with the improvement.
