I think Bair is a red herring, it was made clear that he was here on washers, he isn’t taking up a wage that could go to someone else. The idea was that he would be moulded in the background and see if he could be turned into a player.
Then everyone got injured.
He has proved to be more effective than a couple of the other strikers so he has stayed around the squad.
If we are criticising signings there are many other targets who were signed as first team players.
