3 colleges in 5 years not a great sign.
If you look at WHY he had three colleges (first college was going to re-rate back to Div III and then he wanted to finish career with his dream school growing up) then I think it's a bit more acceptable, even though it's not often seen...
As for all the guards, I know what Boti is saying, but Madgen was played at the 3 a lot last season, so while Sanders, Gleeson and Carmouche are all strictly guards, that SF position is still also fairly well served with both Madgen and Harvey spending time there last season (which I wasn't a fan of, as defensively, they got beat a lot and more pressure on Madge to defend bigger players to take his energy from the offensive end) and also Hill now adding some depth, who then fills out some time at the 4 as well, with Garlepp starting at the 4, maybe needing to fill in at the 5, but with AJ being able to move to the 4 if (God forbid) Allen actually starts to be productive, I think while still thin, it might be ok... But as D4444 says, a lot rests on AJ being tougher than his old reputation would give him credit for...
