He had a poor game against St J, but has delivered in games last season, if he was as bad as you think then the club wouldnt have kept him for this year. There are others who IMO have performed worse this season and still get touted for starting positions.
Personally I want to see the best team start for the tactics we need to win, an experienced team who can go to Dingwall - last away game we were out muscled and over run in the midfield - teams know if they kill our 3 of Doran, Ross & A.N other then Billy gets no service - we need to control the midfield and get Foran using his physicaility to support Billy and hold up the ball.
personally I think he is not that good but he has had a few good (especially the game against Dundee utd last season) games and probably if he had more game time he would be a better player.
