The problem with Gibbs is not a lack of scoring. You can live with 9 points on 3-5 shooting if he had 5 assists but he only had 1 assist while Jalen Adams, playing less minutes, had 4. Gibbs is not a point guard and he is miscast in that role. If he is moved to shooting guard or 6th man he will be better and the team will be better.
Meanwhile with Purvis you look at the boxscore and it looks pretty good- 19 points, 7-13 FGs, 4 rebounds, 4 assists, but the truth is about 4 of those missed 6 FGs should have been finished. And for the season he is shooting 52% on FTs after the 4-7 last night. Not acceptable for a starting guard!!! He has to do better than this. I tend to think he can do better than this. His defense is pretty good as well and that can't be forgotten if we debate whether to sit him or Gibbs so Adams can start. But honestly despite the freshman mistakes that Adams is making, I would prefer him to start right now.
