Has McCollum taken any team to an NCAA Tourney?
If he has, what’s his record in that tourney?
Has a McCollum team ever been to an Elite 8?
Has McCollum ever been named conference Coach of the Year, for a major D1 conference?
How many D1 programs did he serve as an assistant for?
They both started their careers at the same time, Arch just had a better track due to many factors - he came from a well-known basketball family, and played for NC State, an ACC basketball school. He then was an assistant at Western Kentucky, NC State, AZ State, Ohio State, and Arizona before he got the Dayton job, where he went 139-63, .688, 4 trips to the tourney in 6 years and an Elite 8.
Ben may be a better coach, but he hasn’t proven that yet and doesn’t have Archie’s pedigree at this point. As I just showed you - it’s not even close
