There’s already been some discussion in the comments about Nick Cafardo’s last article, specifically about this paragraph:
The Yankees could easily get into the Roy Halladay hunt if they’re willing to part with Phil Hughes or Joba Chamberlain, which they apparently are. The one player they’d love to hold on to is Austin Jackson, their future center fielder who could keep their outfield costs low.
Seems to me that getting Halladay would almost certainly cost one of the Yankees top young pitchers, and that young pitcher would be replaced by the new ace, which make it easier to give up either Hughes or Chamberlain. Replacing Jackson is tougher for the Yankees because they don’t have nearly the same outfield depth in the system.
Aside from guys like Derek Jeter and Mariano Rivera, it’s hard to label anyone as untouchable. It’s a matter of finding the right deal. No doubt the Yankees would rather keep Chamberlain and Hughes, but for an ace like Halladay, they might be willing to deal one of them. They’d certainly rather keep Jackson as well, but for a young outfielder — there’s been a lot of talk here about Curtis Granderson — he might become more available.
I don’t know whether the Yankees are actually willing to trade Chamberlain or Hughes, but I don’t think the idea of moving one of them for Halladay is outrageous. It’s probably necessary for such a deal.
