My biggest gripe... "this just in..." used over and over again. As in "This just in, the Texans are a horrible team". Otherwise I think he is OK (prefer Andre Ware's commentary). All announcers like to have a catch phrase they are associated with... so I don't get upset as much with the "Rock and roll" though I would have tried to some up with something more associated with football or Texas.
My point is that he's always trying to paint a pretty picture of the Texans and sees the team through rose colored glasses. It gets ridiculous when the team is this bad. Remember when he got so upset with a caller saying Schaub sucked that he went off on him, and said "you suck, bye!". He gets way to defensive over the Texan players, just be objective, fans have seen for years what he refused to accept about Schaub and it's now unraveled.
I prefer his play-by-play to the tv guys any day. I don't listen to his talk shows so no comment there.
