Give Chief a spleaf is probably more like it.
He was a great Celtic no doubt, but the rumors used to be that he was a big time pot smoker. Dont know if they were true but in the eighties around Boston, he was one of several players that were supposedly seen multiple times at parties with the weed.
Also as stated, if he was capable of coaching why hasnt he already stepped up? The money will come if he is any good. I would say that Danny knows what he is doing on this one.
I agree about the whole if he was a good enough coach he would have a job right now, but I don't care one iota if the guy smokes weed. I don't see how that would really affect his job performance.
I really like when organizations keep around or bring back guys who've been a big part of their organization over the years, but I don't think you have to waste coaching spots/salaries on them.
Let the guy stay a special consultant to the team and have him come to a few practices to talk shop with the kids. If any of them really click with him they can form their own mentor/mentee relationship, but unless he is particularly skilled at teaching young bigs, I see no reason to bring him as a coach for reasons other than sentimentality.
