Back to my point, maybe we should have a little more patience. Look how many years it took Lou to get Illinois to be a top tier program. Or better yet, look at Coach K's first 3 or 4 years at Duke.
Please, please, please stop using Coach K as a comparable. I think Coach K started at Duke in 1980 and by 1982 landed one of the best recruiting classes in the country:
He landed a recruiting class in 1982 made up of Johnny Dawkins, Mark Alarie, David Henderson, Jay Bilas, Bill Jackman and Weldon Williams. It was rated one of the nation’s best and put Duke on the map to stay.

That's why people were patient with Coach K - they saw the future would be good.
Lou Henson also gave fans lots of reasons to believe the future would be brighter. He landed Levi Cobb from the CPL in his first year and Eddie Johnson in his 2nd year. Both would have been 5 star players if they were ranked. His record also showed a steady progression of improvement.
If K and Lou are the standard then they make the case that Groce is not improving and should be fired rather than retained.
