I think they played Garratt irrespective of Richards hoping to get a transfer fee for him, but in reality nobody is going to pay for a below average keeper. Richards was and is the better keeper, would like to see Will given his chance he looks to have way more potential than Garratt ever had and look how many games Garratt racked up. But taking your point 1 injury and you are very short unless one of the other youth keepers is showing potential ?
