Until 2 weeks ago, I didn't feel the urge to hit the "mute" button on Cris Collinsworth. Randy Cross? Most definitely. Phil Simms? Yup. Dan Fouts? Uh-huh. Dan Dierdorf? *nods*.
When a team is down by 3 scores in the 4th quarter, no drive that ends in a punt can -- with any credibility -- be characterized as a "good drive". And an announcer who makes that assertion is going to lose a lot of credibility. No points + crucial time taken off the clock will always = FAIL.
Now, I'm not gonna go on twitter to trash Collinsworth -- but my opinion of him as a professional sports announcer is diminished.
