IMO, the first group (Hammonds/Sally/Harpring) were program transcendent type players, whereas the second group (Geiger/Schenser) were very good players who were more secondary options that made the sum of the parts greater.
Moses, IMO, fits between the two groups. The first group defined GT basketball during their eras. We're talking about guys who helped carry the program on their backs for multiple years at All-ACC/All-American levels. Moses is a VERY good player, but his impact on this program has only been felt the last 1.5-2 yrs in terms of being the force he's become. He'll go down as one of the better big men to play for us, easily, but just a level below the first group. I'd put him at the Malcolm Mackey/Alvin Jones level.
That's not taking away anything from Moses...that's just saying the quality of players he's being compared to is really high, that speaks to how good GT basketball was at one point (and hopefully we will get to in the near future). GT has had some really good big men.
