I am always amazed how quickly people will brand a player a flop.
Under normal circumstances, I think a player should be given at least half to a full season to settle in to a team. Of course when a player is coming from a team within the same league it is usually quicker. However, is everyone forgetting what this guy is coming back from? Was it not an ACL tear? Who was the last player to come back firing on all cylinders after such an injury. While I was expecting a bit more form Isla from now I am willing to give him until next season.
