I believe, after 4 full seasons, Lavin is a mediocre COLLEGE BB Coach. His record says what he is, here at St John's. The things the fan base here have overwhelmingly voiced is he doesn't make Players better than when they arrived. And, forget Harkless. He was a exceptional talent, already for the NBA under one and done.
I'm also not a worshiper of his motivational skills. I think he's overrated. Hasn't really been able to get his team to win Clutch games consistently.
I think a lot of people confuse a good salesman from a good sales manager. They are far from the same thing. A good salesmen sells, a good sales manager assembles the right team(sports or otherwise) and motivates them to be successful. Lavin is a good salesman.
