I don't mind him throwing a bunch of crap at the wall and seeing what sticks, as long as it doesn't keep him from getting a real arm via trade. Brad Hand was found off of Miami's scrap heap. There are other stories like him too. relievers are fickle.
Do you really want to trust a fickle reliever in the 6th inning if a wild card game?
The time to throw crap at the wall was May and early June. Its July, you're barely hanging on, you've already lost over a dozen games because of this pen, and every other team in the hunt is going to be making a move.
