Bednar wouldn't hurt my feelings here.
Regarding prospect "availability", you trade away pieces for anybody you think will make you better, even if it is for middling relievers. The issue is whether the team believes in the the prospect. Don't get me wrong, I am not planting my flag on this Trevor May proposal, but a guy like Canterino is not close to being a useful piece to a big league club. He is what, our 15th ranked prospect? Injury prone as well... Are we saying do not trade the 15th best Twins prospect for useful big league piece? (Arguing for/against May in this spot is semantics). I would have a hard time buying into that. Regarding Ober, I am of the belief he falls into that 4-5 SP category. Not hard to find. (Again, my opinion).
