I agree with you on that we don't need him. He seems to get burned quite often, and the only thing he has going for him are his speed and hands. He's more of an interception master than a good cover guy. But that's just my opinion ofcourse.
I'm sure he'll be signed soon enough again though, since he might be an upgrade over quite alot of guys atm, especially since he returns quite good aswell, just not on a big contract anymore.
