Both he and Weber also had some bad luck or made some bad gambles that blew up in their faces. Weber had the great 2010 class that included a psychopath, an effective one-and-done and a damaged athlete. As you noted earlier, surrounding that with empty 2008 and 2012 classes really hurts the program.
Then Groce decided to go quick fix with transfers and had similar luck with Cosby, Paul, Starks not going quite according to plan. That's a bunch of scholarships spent with hardly any return. Then he chased high end PGs and got left with nothing there as well.
I agree on both points, and at the end of the day, it is always who you end up getting and how they perform (including off court problems) more than who you miss on.
I like Groce's current class much more than others, it is not as great as others make it to be, but it is solid positionally balanced class. Unfortunately, I believe it is the kind of foundational class that Groce needed in his 2nd or 3rd year, not in his 5th.
In retrospect, many criticize the hiring of Groce as an obvious bad choice. He was not an A+ choice (i.e., Smart, Stevens) but I thought the list below that level was a lot shallower than this year so Groce became an option. He also showed a lot of promise early on, he coached well his first year, motivated, and was riding high with fans and media as an overachiever. He looked like a potential star, Klee made a statement if you remember implying that Groce was destined to move up from UI. All that IMO, probably got to him, made him overconfident, started chasing the quick fix and grand slam HR's, getting him away from a recruiting plan and roster strategy that could have worked.
