I think there's a bit of damning with faint praise with regard to the Under 21 record caps holder. It's usually a player who breaks through at a young age but then doesn't kick on to the senior squad as soon as would have originally been expected. Lee O'Connor is probably a prime candidate in this squad as Coventry may get promoted soon the way he's going at club level.
I don't think most of the players who have missed out can have too many complaints. Noss and Johansson haven't progressed at club level and McEntee isn't that good - he strikes me as a bit of a poor man's Shane Duffy who doesn't really fit the way we want to play the game. Will Ferry must have been close to a pick though, he can possibly feel hard done by.
