SS, I really respect your input and I agree with your reasoning, BUT this poor kid doesn't seem to be worth much to the vast majority of the posters on this board. This is not a putdown of your contributions which, by the way, I almost always appreciate. If he reads these posts, I wouldn't be surprised if he is getting the same impression that I am: "he's no good and we don't want him here".
Evidently Tubby sees something in him that the fans just don't appreciate yet. I think that he can make a contribution and, in fact, already has. I noticed that I no longer get anxious when he gets the ball, for fear he'll turn it over and he seems to fit into the flow of the team on the floor.
Has he earned significant time? Not IMO.
Does he have 5* upside? Can't detect it.
Is Tubby willing to help him develope? Looks like it.
Maybe we should just accept that he'll be part of this school until Tubby decides no.
