Magic is kind of a joke. ESPN is behind the curve, but I actually don't mind Van Gundy. He's a bit obnoxious, but he knows his stuff for sure.
CBS has good people. Clark Kellogg is amazing. Marv Albert is great. The basketball commentary is much better than the NFL commentary. Plus they do NCAA ball too, so you get quality there. More carry over between the levels of the sport whereas only a few NFL guys do CFB.
I will say that there are several CFB commentators I enjoy. I even enjoy buffoons like Lee Corso and Lou Holtz in small doses. Just way too many NFL guys I can't stand.
