It's wrong but natural isn't it. In any walk of life, if your boss is prepared to make a financial commitment towards you, then you will certainly get the benefit of the doubt more often. It's also the other way, people think "I can't afford to get this one wrong".
I happen to agree long term Godfrey is a CB, but I don't think a run at fullback will do him, or the team any harm. We have been scrambling about for a tight defence for some time, and we have had a couple of decent performances there from him. It reminds me a bit of the Lescott, Yobo, Jagielka & Baines dilemma. We all knew long term the best solution was Baines, Lescott, Jagielka, but all the while Lescott, Yobo, Jagielka performed well, it was stupid to change it. Allow Godfrey to really build his confidence at fulback and then move him inside once he's built that rep/confidence would be the most likely avenue.
I don't foresee Brainthwaite going to fullback. But he's a like for like in the middle, if we don't want to tamper too much.
