They’re better, probably, but I do question how coachable John Wall is. The criticisms of his game have persisted through three head coaches, namely that he takes defensive possessions off and gambles too much on defense in general, and frequently clashes with his teammates, forming us vs. them cliques within his own locker room, which he then tries to paper over by buying all his teammates expensive gifts. He’s very prone to hero ball, and while he is capable of heroics, more often than not hero-ball is unsuccessful. I’ll put it this way — if Wall had been a Celtic during the Stevens era, I think Ainge would have traded him.
Many of the same criticisms can be given to Beal as well, although I think he’s probably more coachable than Wall about these things, and followed Wall’s lead.
The Wizards in general have been a poorly run organization for over a decade, and I don’t know that Stevens would have even left Butler to take that job, in an alternate universe where it was offered to him. The organization doesn’t have long-term plans, and instead just tries to patch things up year-to-year. The Wizards would have likely been better, because Brad is a terrific coach, but, for example, I don’t think last year’s team would have won 55 games with Brad at the helm.
