This would be a great time to deal Quentin. Kenny can even bring up Viciedo to play right and pretend he's still all in.
At the very least, they should trade Jackson for a right-handed reliever and a prospect, and then bring up Viciedo and send Sale down to get stretched out for when Peavy goes down again in case he's needed to start for them this year.
I can sympathize with that if its ones opinion that right around the corner Peavey is going to breakdown.
