If that's Sitake, and that may be so, then sign him up. Lots of coaches can succeed with good players. Few, if any, greatly exceed the level of their talent over time.
I do believe Sitake would need some excellent assistants. So make that part of whatever interview process.
Bronco has earned the chance to right the ship. But he's also earned scrutiny and the expectation that we get better ASAP. Makes perfect sense to be looking for potentially better options at this point.
