Agreed on Zaidman. Unlike several of his peers (Benetti included), his "announcer voice" and general smarmy bearing are a continuous advertisement for I went to Syracuse to become a broadcaster, and he's also one of the all-time hilariously cliched apologists for any team he covers -- Cubs, Bears, or DePaul. An immediate "change the station" guy for me, when he subs in on Mully and Haugh, that's a morning I won't be listening to that show.
So yeah, compared to him, McKnight's a dream.
