I don't think there are many who question his commitment, it's his ability that is contested. He tries hard and gives his all but, technically we need an upgrade and have done for years. IMO. Would never wish him ill though.
Sean Flynn was a committed trier but I wouldn't want him in our midfield either.
Molumby showed on Saturday that you can work hard and be technically good. Not saying that one game makes him a world beater but he certainly deserves to keep his place.
Snodgrass also showed that it's not all about legs and pace, a footballing brain can compensate for that.
I think bringing Jake back would set us back, without a doubt.
