One of the best, for sure.
I re-watched Stupor Bowl XXXIII (Broncos beat the Falcons - yeah!) recently. Summerall and Madden called the game. Summerall was perhaps the classiest announcer I can remember (only Martin Tyler of soccer comes close). Madden, on the other hand, can't stop talking. I forgotten how much he dominated a broadcast with his incessant chatter. I still like him, but he needed a mute button now and again.
RIP, Pat.
