I would give McCollum A-, and DeVries B-...or maybe incomplete grade for DeVries, actually.Not sure how you can make McCollum an A- and Devries a C+. Not at this point at least. McCollum may very well end up better, but not by a while letter grade at this point.
I get the concerns with his D2 record, not being applicable to high major D1 basketball. But you can't just ignore that those seasons and accomplishments happened. And then when you actually read up on him, and listen to him talk...at least for me, it solidifies those accomplishments, and gives context and ideas on how they happened.
DeVries has a lot shorter head coaching history, and hasn't accomplished nearly as much as McCollum has. He does have 1 year of high major ball now under his belt. And I think his team's performance pre/Tucker injury, shows that he's capable of making that step up fairly successfully.
But his resume isn't even close to the same level as McCollum's is.
