In the debate over the best PG of all time there are really 4 tiers...and the first tier is exactly 2 names, although the order varies depending on who is talking: Magic Johnson and John Stockton. Tier 2 you get into guys like Isaiah Thomas (the first one), Steve Nash, Oscar Robertson, Jason Kidd, Steph Curry, could argue that Westbrook belongs here too after his last season and a half, etc. Tier 3 are the solid guys you would want to build around but not necessarily among the best of the best ever, like Chauncy Billups, Cousy, Frazier, Dennis Johnson, etc. You could further stratify this on down, but from here down the arguments get wide and varied, but the top 10 generally are set. If "all" we get out of Mitchell is a top 20 PG, even if he falls in the subjective 15-20 range, then holy hell what a steal. I think he has a chance to climb into the rarified air, but only time will tell.
Right now to me his ceiling is probably Westbrook-ish, seems to have a similar game and I think he will be one of these guys that can average 20+ PPG, 5+ RPG and APG, 2 steals or similar. His floor, barring his rookie year being just a flash in the pan or injuries, is probably on the order of Wall or Arenas or Kevin Johnson. Not that I think his game is like any of theirs particularly but rather just his overall level of talent and ability would fall in that range on the low end.
