Ok CAAR this one is easy.
So Erb deserves no credit for Greene? Why is that? If Greene would have flamed out, you would blame Erb, but since he did well, you want to ignore it? Seems like a double standard.
How about we look at the facts:
Erb move to RB's coach, and the only player they had to tote the rock was a kid coming off 2 years away from D1 college football, and was so out of shape he was barely ready for the season. Yep, sounds like a terrible job coaching the kid up to being the Doak Walker winner. At the same time he is developing a good backup in Jewel.
Fast forward a year. Greene leaves a year early, and Hampton goes down to injury. Erb has to take two FR RB and teach them the system, and make sure they are game ready. The two RB combine for 1 turnover all year, the Hawks run the ball effectively all year with the FR, and they win an Orange Bowl.
Fast forward another year. Whegher leaves, Hampton down to injury, he is left with Robinson. This is not a highly recruited kid, and he turns in a very solid year. At the same time he is bringing Coker (also having an early season injury) along nicely...so much so that when Robinson is dismissed from the team, that Coker sets a bowl record for rushing.
Fast forward another year. Coker returns, and has a good year for the Hawks.
Next year he will need to do ANOTHER good coaching job to make sure we have FR or kids with little to no experience can tote the rock.
Now if you want to put all the blame on Erb for Whegher knocking up his girlfriend, blame Erb for Robinson smoking the herb, for McCall having an off field issue, for Coker having an off season issue, then you have that right. You say he isn't enough of a "mentor". Well the fact is Erb can't be with these guys around the clock. Even good kids do drugs in college, even good kids get into trouble. He doesn't have players leaving because they don't like him, they are having kids leave because they get into trouble off the field.
Honestly none of us know if the kids like him or not. We don't know if he is a great recruiter, or is he is a good X and O's guy. You are simply making a blanket statement that since kids have gotten into trouble, it is HIS FAULT!
