I think he's worth more than a 5th...but I wouldn't trade him for just a pick...try to get a vet at a position of need and a 4th or 5th.
Just like xCSP you own the "asset" you control the value...I still think we got robbed in that trade because we let everyone and their momma set his value. A HC with the balls to eat RWs contract and run him out of town is worth more than a lousy late 1st rounder
