We are well stocked at point guard. It's not like we are trotting out Bender or Chriss simply because we drafted them high. The same was true of Jackson until a few games at the end. Harrison and Canaan were both positive factors when they were on the floor last year and Harrison was a positive factor in SL - Jackson was a disaster in SL, but we can overlook that because it was clear he was trying to do too much. I suppose it's possible the absence of Booker may trigger the same response in Jackson again, but I think Igor will nip that in the bud.
With Booker possibly missing the opening game, we have one proven successful player in Ariza, and he may be moved out of his position. We have a fair idea of what we have in Warren but it's not clear he's a positive contributor - for instance, last season, his +- was worse than the team average of -9.2/48. Beyond that we are betting on the come at every position. I expect Ayton and Bridges will be positive factors as the season goes on and I have hopes for Jackson. For Anderson and Bender it's more like wishful thinking as they've never shown themselves to be positive factors.
With a team like this why is everyone fretting over the PG position? Canaan may take time to come around but I expect Harrison to continue as has done in the past. The odds are that the PG position as it stands will be carrying the rest of the team out of the gate.
Interesting note: Among the nine players whose +- was at or below the team average we are shedding six of them. Len, Ulis, Dudley, House, Williams and Peters. The other three are Booker, Harrison and Canaan. Granted, most of those we shed were low minute players.
