I didn't want A-Rod a few years ago when the Mets had the chance for the same reason the Mets didn't want him.... the entire team would revolve around him and we wouldn't really get to appreciate the dynamic of youngsters Wright/Reyes or give Beltran his chance to shine last year.
That said, I think A-Rod's time with the Yanks was a humbling experience for him; but Boras is still his agent and whose to say that NY isn't just NY? Plus, the Mets would not move Wright or Reyes... I think that would be dumb, and I just don't see A-Rod moving to 2B at this point in his career. SS to 3B is one thing, but the other side of the infield is a whole different ballgame.
I say, let a small market club duke it out for him. We have all the offense we need.
