Should i trade Tim Lincecum for Jared Weaver?

Hanley is easily the best SS in the league, which is also a premium position, not too many stud players here. I would never trade a sure thing like you have in Hanley for nothing less than a sure thing back. Sure Castro is good, but the Cubs are god awful and he's had 1/2 a good season under his belt. If you do want to move him though, make sure you get a top 5 guy in whatever position you're looking for. Nothing less than top dollar for Hanley. Also, although Weaver is a top 5 pitcher in the league, he's very very good, Lincecum is a top 2 guy and better. It's pretty much a side ways trade. Yes Timmy is having a rough patch right now, but don't sell low on him. He's an absolute stud and he's young. I'd hold still and not make any moves unless you 100% win the deal.
