Biggest issue I've seen is that he sometimes makes his mind up before the play.Luton may never be great, but I think burying him after today is premature. He has shown some ability IMO.
He also left some points out there early when he was a little too keyed up and had some overthrows. If I'm being fair, I'd say that he's likely going to be a pretty significant upgrade over last year as this season goes along.
