So, here's my follow-up question. Does it seem like some people in this thread think that Ainge was primarily a point guard?
I think he was a combo guard, leaning toward SG.
It's interesting that basketball-reference.com lists Ainge as a guard-forward. Perusing the stats, when Ainge first started for the Celtics, it looks like Quinn Buckner and Tiny Archibald were the PG starters. Later, Ainge started next to Dennis Johnson, a shooting guard who became a point guard. When traded to Sacramento, he started next to Kenny Smith, who was clearly the PG there. When he went to Portland, Ainge came off the bench but Danny Young seemed to be the main back-up point guard. In Portland, Frank Johnson seemed to be the back-up point.
So, it appears that Ainge was mainly a shooting guard throughout his career.
