I'm not saying that it's a disservice to associate Drew with these two coaches, but it is a disservice to not lump Barnes and Smith in with (or even above) Kruger and Huggins. Bill Self's in a category unto himself at the top. Barnes and Smith have combined to take seven teams to the NCAA tournament and go 1,131-550 (.673). That winning percentage is identical to Hoiberg's, but sustaining it over multiple decades should get these guys a lot of credit.
However, I would venture to say that Barnes has higher rated classes year in and year out and mostly underachieves. Smith? Once he didn't have the Kentucky-type recruiting classes, he has been pretty underwhelming as well. I guess I'm viewing these coaches as to where they are now or maybe even the past 2 or 3 years. Kruger, Hoiberg, and Huggins are just able to do more with lesser rated recruiting classes.
