If he's willing to sign for veteran minimum, then why not? If it doesn't work out and/or his presence in the locker room is really cancerous, then just dump him early on. Otherwise, if he's even a bit engaged and acts mature, could be a big get for us. Guy averaged 17 and 13 last year and even in limited minutes could probably average something like 12/10.
If we lose Baynes, we should look at this option, or we could re-sign Baynes AND bring in Howard. Our front court AND back court will look like elite units
