DeGale did look shopworn , but we shouldn't take away from Truax's performance, I think the guy deserves a bit of respect. DeGale couldn't really wait , I don't think it's his choice when he re-activates his rematch clause , it's either "do you want it or not?" he had no choice really. Either he's at the level or not and there's only one way to find out .
Also , i don't like tearing into people for the sake of it , but I don't think he gets anything whatsoever from his trainer. It wouldn't hurt him to go with a strict disciplinarian who fucking tells him exactly how it is . Somebody who can stand up to his ego.
He could come back and be a force, but it'll take a lot of humility, hard work and soul searching. without knowing the guy personally, i don't know if he's capable of that.
