t the job it was pretty much assumed that he'd have a learning curve ahead of him. This is part of it. The Skiles, get in your face, approach works for a limited period of time, then players tire of it and the team ends up underperforming once again and Skiles is out the door.
Yes, Brad could well stand to 'grow a pair' in terms of dealing with players and also start working the refs a little more than he has, but assuming he wants to be here, I would give him time. Its not like this a championship team that's under .500 because the coach can't get them to play.
Showing leadership doesn't mean he needs to get into anyone's face. As a matter of fact, that's probably one of the less efficient ways to be a leader.
But there are simple things he could do in order to establish credibility. For example, have basic, clearly outlined expectations of players -- including effort, defensive assignments, shot selection, plays, etc. Reward guys that meet said expectations, send a message to guys who don't.
Of course, Stevens seems to fail miserably at the later because he seems to have a very limited idea of what the former is. I don't think he knows who his best scorer is, or how to get good scoring chances over the course of a game. He seems to lack a core defensive philosophy, or at least has no idea how to translate his intentions into on-court performance.
The only time this team goes on the run is when (a) a shooter gets hot, or (b) someone gives you a great one-on-one defensive performance. Both of these are bound to happen from time to time over the course of a long season, but it doesn't exactly scream "well-coached team".
