I think we should keep him - having someone who can play both FB positions at a decent level is helpful when considering how long the season is and what injuries can potentially occur. When he stepped in at LB this season for an injured BAE I thought he did well - the only bad game being the one against Woolwich where he pretty much had Sagna and Walcott overloading on him.
We'll agree to disagree, but I do think that he should be given more opportunities to start ahead of Walker who has, quite frankly, been dreadful this season.
IMHO that's where the disagreement comes from.
I quite simply don't think he is playing at a "decent" level and that he has only had one poor game (our last one being a brilliant example).
