I think if either of the teams acquire Clemens, as most have said, it'd be the Yankees. But then who could they give up for him? The aforementioned Robinson Cano or Chien-Ming Wang -- and if they want to give up those two, I'm all for it. Wang has been their best pitcher and he'll just get better and Cano has been solid.
The Yankees acquiring Clemens would just be another step towards their demise -- it might hold it off for a little bit, but it's inevitable. So it goes when you have a depleted farm system and an old team.
