The guy wrote "where Lavin has proven he can't and won't be great". So, I merely pointed out that in his first head coaching gig Lavin was in fact great. In his second coaching gig, he has not yet been great but has brought the Johnnies to 2 Ncaa tournaments in 5 years following a 7 year tournament drought for the program.
Same difference as when a guy implies that Phil Greene was only good this season for 3 minutes in December and I point out that he led the conference in 3 point shooting in league games that all took place after December.
If people didn't type out their a$$es so much, I wouldn't have to disprove the excrement with fact.
I think that one could easily argue against your point, based on the fact that Lavin, during his tenure with UCLA had two #1 recruiting classes, and perpetually had a top 5 or top 10 class. If you have the best college kids in the country at your disposal, and you can't get past a top 16 ranking, then you are not "great". Now would most schools like to get to the sweet sixteen every year, of course, but great coaches don't fail to meet expectations for 6 years, and get to be considered great. College's don't dismiss their HC when he is great, unless he continues to embarrass the university. Lavin, "great recruiter", probably when motivated. Great coach ... not so much.
I'm sure your opinion will vary.
