Agreed.
The article summarized what I've heard about Brown's departure -- there was lots of team dysfunction, his coach [and the AC who recruited him] had both left, 4 out of 6 members of his incoming recruiting class were leaving. Syracuse wasn't close to sniffing the NCAA tournament his first two years, and he wanted to taste that success. All while getting paid substantially more.
Wish he'd stayed, but understand why he left. However, it does suck that he went to an in-conference foe, ESPECIALLY Duke.
But Maliq was a terrific player to us, who's value often went beyond just stats alone. I think that's why it is easy for some posters to rationalize away the impact of his departure.
