Rondo (or another assistant in the pros of similar high caliber quality who knows how to coach and wouldn't tolerate lackadaisical attitudes) could be brought in mid-year.
And that would be the best thing.
Waiting until end of year on a current head coach, means starting over trying to keep whichever current players wanted for next year, as well as hopefully keeping the two HS recruits (and maybe giving us a chance for others Pope couldn't get).
Plus, Batt could get him (or someone like) for a two or three year contract, vs. having to offer 5 to 7 years to an established head coach after the season ends.
Someone like Rondo should be able to keep the two assistant coaches now who have value for recruiting and player development, while getting rid of dead weight like Mark Fox right away.
We don't want people in the program who talks about being a "Swiftie" and how wonderful everything is and is going to be. We need a kick *** and get the hell out of here if you don't want to give 100% on defense coach.
All these other candidates mentioned in this X post, AS head coaches, would need to be hired after the season. And that means starting from scratch once again for getting players. Bringing a rising assistant in mid-year, gives the chance of keeping the best players who will respond well to actually being challenged by a coach who doesn't want to be their best friend.
