Sure, UNLV under Tark, Memphis under Cal, UMass under Cal.
As far as Calipari winning at Memphis and UMass, his winning at those places doesn't scream "cheating". He may very well have cheated, but just because he won at those places doesn't mean he cheated.
Memphis had a strong MBB history prior to Calipari. Unless Bartow, Yater, Kirk and Finch were cheaters, it would seem that winning at Memphis doesn't require cheating. At least as I look at Memphis history, somebody winning there doesn't scream "cheater". The program had been "down" for at most two seasons, which certainly wasn't like Baylor was before Drew got there.

Only one player that Calipari coached at UMass (Marcus Camby) made it to the NBA. From
John Calipari - Wikipedia, the free encyclopedia
In February 2010, Pat Forde, writer of a regular college sports column called "Forde Minutes" for ESPN.com, vividly recalled the 1992 team:
“ Calipari's greatest strength as a coach is his ability to create teams that play together. His 1992 Massachusetts team remains one of the most overachieving units The Minutes has ever seen, featuring a shooting guard with range so limited he made one 3-pointer all season (Jim McCoy), a 6-foot-3 power forward (Will Herndon), and a left-handed center who stood all of 6-7 (Harper Williams). Somehow, that collection of marginal talent went 30-5 and advanced to the NCAA Sweet 16.[5]
If Calipari was cheating to get big-time talent at UMass, he certainly wasn't doing a good job of it. He won at UMass by overachieving with average players. It looks to me like Calipari did a great coaching job with average players at Umass. Again, not saying he didn't cheat there, but what indicates that he was? He certainly didn't have great talent on his teams.
In addition, UMass had a good MBB program up until the late 1970's, about 10 years before Calipari took over. The coach who retired in 1978 had a 0.612 winning % over 13 years. Dr. J and Rick Pitino played for UMass, so there was some MBB history there. It took Calipari three years to win a conference title in a not-exactly-powerhouse conference, and 5 years to make the NCAA tourney. That's not exactly a quick transformation.
Tark may be a good example, though. Before UNLV, Tarkanian was 102-20 at Long Beach State. As soon as he left LBS in 1973 for UNLV, LBS got on probation for recruiting violations that went on while Tark was there. And later UNLV got in trouble as well for things that went on while Tark was coach.
