I think i just figured out why KW would make this trade.
KW keeps saying he needs to be "creative", he's made it clear he wants Kenny Rogers (but dosen't have the money).
So, he trades Jose and his 5 mil (+ Rauch or the deal dosen't happen) for Rollins. The Phillies are then glad to take the 5 mil, because there getting a stud prospect. This gives KW about 4.5 mil in extra money, which he can use to sign Kenny Rogers.
Any thoughts?
