Wells, who still has $107 million remaining on his contract, is certainly not your typical throw in. Should this be the case expect this to greatly narrow down the teams that could possibly acquire Halladay. It probably would make only the Yankees, Red Sox, Mets, Dodgers and Angels the only contenders.
If you were thinking no way the Jays would trade Halladay within the AL East, think again. Blue Jays GM J.P. Ricciardi made it clear that he has no problem moving Halladay to either the Yankees or Red Sox.
Halladay, who does have a full no-trade clause, likely would want to agree to an long-term extension before accepting any trade, which would make any package with Wells astronomically expensive.
I think the price for Halladay alone is probably going to be off the charts, so if Ricciardi demands Well's in the deal it's very unlikely that anything will actually happen. Unless of course a team can convince the Jays to take less in return in exchange for Well's contract, but that scenario is doubtful. For now we'll just have to wait and see.
