As a Xavier fan, I don't post here often. I've read through a decent amount of the posts so far in this thread. With that being said, I think Mack did lose control of his ballclub for a period of time last season after the shootout. They did show a lack of maturity that a senior laden team needs in order to put something like that incident behind them. I would be lying if I didn't, at times, begin to lose faith in Mack.
With that said, and I know people will go straight to pointing to the fact that they played a 15 seed in the tournament to get to the sweet sixteen, but the fact remains they were there. They did come together towards the end of the season last year, and in many cases, Mack did out coach his opposition. Which was something that we, as Xavier fans, had not experienced a ton of during the season.
Sometimes it takes a young coach time to find his "sea legs" and learn how to coach, and how to truly take that step from the top assistant to the head coach position. I know Mick has done it, but he absolutely had to go through some growing pains as a coach, and the dismissal of Alvin Mitchell is a great example of this.
Lyons brought a ton to the table athletically. He was loud and I can certainly see where he could get under a lot of people's skin. He will get his degree, and move on to another program. I think his dismissal however, is another sign that Mack is taking that next step in becoming a good coach. Sometimes tough decisions need to be made.
Finally, Yes, those players that the greatone pointed out did transfer out of the program, but in each one of those instances (with the exception of Lyons) that player was not going to see significant time throughout their career. This can happen for various reason, but Canty and Latham both left to be closer to home, and Mckenzie was the product of 3 months of AAU ball. I'm not saying that Mack is at the point where he is a great, or even a good coach, but as a fan of the program, I do believe that he is taking the right steps to becoming a more complete coach.
