Yes, Smart has been up and down. I said so myself in response to someone listing him as a candidate.
He's not my number 1 choice. But if you don't cherry pick JB's last 2 tournament runs, Smart has been somewhat better, despite having a bad spell at Texas and getting fired.
So, just to be clear, over the last 6-7 years, JB's record is worse than a guy who was fired, and is at his rebound job.
Certainly Smart would have a more promising future than Boeheim at this point. That's undeniable. Boeheim won't win 20 games again, no matter how many years he wants to stay.
