The problem with Archie and him getting a defined roll is that he does not have the skill set to play any specific role. He can't shoot well enough to trust on the wing, his decision making and ball handling are terrible so you can't trust him on the ball either. And he gambles waaaaaaaaaay too much defensively. He can get away with that in the Summer League but real NBA players are going to burn him on those dumb swipes 9 times out of 10.
He plays totally out of control, at about 150 mph. Against sub par talent in the Summer League and the D-League he can look great, because they don't have the speed to stop him but in the NBA he just looks like a maniac with no feel for the game.
They keep letting him play at PG and handle the ball but I just don't see it. IMO thats what he is worst at. He has zero court vision, he gets the ball and his only thought it to barrel into the rim, a guy like that needs to be on the wing, even if he can't shoot.
I'm not worried about TJ's role though. I think coming off the bench will be good for him and there is a lot better odds of him getting touches and into a flow as offense off the bench than if he was starting along side Bledsoe, Knight and (presumably) Kieff who would absorb a lot more of the opportunities than the substitutes will.
What I meant by a well defined role was a spot in the rotation so that he plays regularly and at fairly well defined time during the game. I'd expect Jeff or one of the assistants would give rather explicit instructions as to what was expected of him when he was on the floor and make him well aware that if he ignores the instructions he will quickly be sat down for that game.
I know that he likes to barrel all out to the rim so one of the instructions might be that he has to pull up for a jumper, say, one third of the time. If he shoots them poorly then he will practice pull up jumpers until he's blue in face - full tilt then pull up. The bigs could practice bothering his shot or blocking it. If he crashes into one then he has to carry his bags on the next trip.
You would think that NBA coaches would be brimming with ideas of how to get players to play the way they want since that figures to be a major component of their jobs. Goodwin hasn't exhibited much learned behavior as of yet - though he did pull up once in the first SL game.
I tend to think in terms of coaching and, right or wrong, I attribute most player failures to poor coaching. It really ticks me off when Jeff starts blaming the players, it's tantamount to admitting he doesn't know how to do his job. Either he isn't communicating what he wants them do or he doesn't know how to get them to do it during games.
As far as TJ getting touches, I'm assuming that Jeff plans to have one of Bledsoe or Knight on the floor nearly all the time. Thus TJ won't really be competing with subs for touches. And he doesn't need just touches, he needs a dsitributor who is well aware of when and where he needs the ball.
You may have noticed during the last two seasons almost every time Plums got a helpful pass it was from Bledsoe - not Goran. Maybe Miles mistakenly thought it wasn't worthwhile to try to get open when Goran was handling the ball or maybe he wasn't mistaken and Goran didn't look for him. TJ won't have be spoon fed to that degree but the same idea applies. He works his butt off finding little openings but the ball handler has to be aware of his movements to get the pass to him in good rhythm.
I'm sure its not what Jeff is hoping for but I expect Bledsoe and Knight to be locked in a battle for dominance. I think it will color their decision making all the time - what is the best thing for me in this situation. A timely pass to TJ is probably not going to wind up being an assist since he is not a spot up shooter so there won't be any formal credit. Thats where the difference between being a starter or a sub would come into play. Overlooking a starter would be a negative mark but a sub, not so much.
