Just to be real for a second....
Vasser was a mistake Yes - in many ways
Lyndsey was an off guard who didn't suck Maybe. He was only good for one season. And the whispers about last season's demise often include his name.
Without Isiah Brown's contribution in a handful of games (Wisconsin) there's an argument that NU doesn't dance He has another bad recruiting decision. SG recruited to play PG. Then, run out because he wasn't able to remake himself.
Ash was top-tier recruit whose ball handling and management did not get appreciably better in college, but he's a top-tier defender Top tier - I challenge. He was filler needed when CCC just starter. I doubt he would be recruited by CCC if he has in HS now, assuming all the same skills.
Greer looks pretty competent and will get better and better Plucked a year too early, we are seeing that is not a good formula, nor is relying on true freshman. He may develop, or may be scarred from this experience. No one knows, but haywood has already moved on and he is right more often than wrong so...
Lathon was an outlier situation But is was more of that all eggs in one true freshman basket. CCC is at fault for not already having a legit LG or PG on the roster. Live and die by the true frosh, CCC got cut. His fault.
BMac locked out others for four years, but got NU to the dance BMAc got us to the dance. I think the Curry camps hurt him, I think overuse hurt him. The only complaint I have about BMac the player is if he was part of the chemistry problem as has been suggested, then boo on him. And boo on CCC for not handling his team better and maybe quit the 20 team captains approach...
I'm old and don't see as well as I used to, but this doesn't look like malpractice to me. I would join you in the argument that B10 guards are easier to recruit through NU admissions than B10 bigs so I did not think guards would be a problem area. And, if the next five years at guard looks similar to the last two then, sure, there's an issue. But I just don't see that Collins has fallen down on this as you assert.
