I think he's insightful, enthusiastic, and upbeat. Says what has to be said, and his insider's knowledge is tops. The fun he gets out of being a fan of the sport comes across very, very well. The stuttering thing ain't going to go away, but I could care less because I think he has such interesting commentary.
Some people won't give him a break if he has to be seen because he doesn't LOOK like like the perfect broadcaster with his bald head. I say SO WHAT to that. Some will never give him a break because of the slight stutter and maybe because of his somewhat nerdy speaking voice. Again I say SO WHAT. But the networks will never hire him. Too bad, but that's probably the way it works.
Keep at it when you can, Alan! And thanks! Big fan of you at the mike!
