I think both the Red Sox and Yankees would be crazy to make the trades proposed.
The Yankees should keep their young talent and the Red Sox don't need the upgrade.
The longer this goes on, the less I welcome the deal. I would prefer no deal actually, only because I really want to see how these kids develop (Lester, Ellsbury, Masterson, Bucholz, etc.)
RB I basically agree but I think the Yankees "need" Santana. The young kids are good, but can you really rely on a rotation of Pettite, Wang, Hughes, Kennedy, and Jabba the beekeeper? Jabba, like Papelbon, maybe better suited in relief, especially if no set up man emerges. Hughes and Kennedy in a full season is a complete unknown. Wang is a quality starter, but not really a dominating #1 ace. He won 19 games, but he has yet to show himself as a big game pitcher. Pettite is aging and had some problems last season. If the Yankees can get Santana for Hughes/Cabrera/Other prospect, I think you have to make that deal. But the Twinkies seem to be playing mickey mouse games. My bet is that they keep him and no deal gets done by anyone.
How about the Detriot Trade? Dontrelle could be a complete bust, but Miguel Cabrera really stacks up that line up.
