KY always brings in talent no matter the coach. Not so with TN so you are making a faulty analogy.
Nope, we've had NBA players here from every coach over the last 50 years. Buzz Peterson flopped with a loaded team his first year. Jerry Green couldn't get over the hump with a ton of talent. Martin had multiple NBA players on the same squad that struggled all season before getting to the S16. Pearl had fewer NBA guys than Martin but still did well with overall talent.
Coaching is huge in CBB. The elite do well recruiting and in the post season. Some knock it out in recruiting and come up short in the post season. Some don't recruit as well but still thrive in the post season.
