if he is burried on the depth chart as a CB 4, it makes sense to trade him for a 2nd rounder. This years 2nd rounder is our starting OG, much more important than a CB4 to our window of success. Next year it could be a starting safety (ours are getting old/injured), or a OL, WR, etc.
I agree he played well down the stretch, very well actually. But what the heck is going on this season that makes him our CB 4??!!
