We also have recent high level success (E8, F4) to point to just prior to that. So yeah, while the program is coming out of its lowest point arguably in 30 years, it was sky high just before that. And in today's NIL/portal age, results can be flipped around immediately (see Louisville).
Again, I don't think it is unreasonable to have expected a little more of the roster and staff be filled out by now. Maybe Lucas is being extra selective based on character, style of play, etc. Who knows. The jury is obviously still out.
