I would suggest we are using a standard distribution across A,B,C,D, and ... Not across every team ever, but across the current teams in high major basketball, because who cares if Girard is better than directional university guards? So an A position group should be a top 20% of all high major groups. I'll call high major the top 10 conferences by NET, although only because that includes the WCC, and thus Gonzaga.
Guards: B
Girard is a proven commodity as a shooter and ball handler (for better or worse) who is moving into a more natural role for the first time, so should light up some score boards. His point guard skills cost us some games, so having Mintz and Torrence to help him improves this group. Mintz is very high upside, but inexperienced at this level, and Torrence is a steady pass first point guard who hasn't done much yet in his college career. Copeland is unlikely to play this year. I think you could argue that this group is better than 60-75% of all guards groups, but 80th percentile seems a big stretch.
Forwards: D
This group has a ton of potential, but has done almost nothing. We seem to have Benny Williams locked in at one forward, but nobody can even say for sure if he's a big small forward or a quick power forward or ineffective. He was a highly rated recruit, and JB seems to have faith he will be good, but his upside hasn't yet come through. Everybody else is a freshman or bench warmer. As it stands, Brown, Taylor and Bunch are likely candidates to be in the rotation, but nobody really knows what to expect from them.
Center: B
Edwards is an extremely solid center, perhaps the best in the ACC. But he is foul prone and his backups in Hima and Carey are largely and completely unknown, respectively. At least neither is 6'9"and 175lbs like former backup centers.
Intangibles: B
This team is way better constructed than last year. Or defense had too little athleticism and we had too many guys who could only help the team by shooting. Our upcoming team has everything. Pick and roll, drive and finish, drive and dish, three point assassins, drive and kick, rebounding and athletes to play good defense again. We should be able to score, even if we can't figure out exactly who is going to score what. But more importantly, we should get better all season long on defense, and not get torched on the boards game after game all year long. And don't get me started again on breaking pressure and inbounding successfully.
