Maybe, but unlike Cook's departure, the fact that Mo went as someone who no one thought would make the jump to the 15th selection overall no doubt has helped and will help Lavin and the staff with recruiting.
I'd like to think that Cook and Hatten would have been a tourney team and done pretty well. Had Artest stayed one more year, I think that team would have been a legit national title contender (I know we were ranked high, and were a legit top 10/15 team that year, but I think Artest would have put us into the top 3 or 4.
