Be more like Tony Romo and less like John Madden.
My all time favorite color commentator was the 1 year Bill Walsh spent in the booth in between retiring from the Niners and coaching Stanford. His pre-snap dialogue and his live-game observations were head and shoulders above anyone in the booth at that time (Merlin Olson, Bob Trumpy, John Madden etc....)
BTW ...I never understood the love affair with Madden in the booth. How did he coach a team to a Super Bowl when all he brought to a broadcast was grass stains, boom sound effects, and turkey legs?? Not to mention he kept saying the Pats were making a big mistake by going for the win on that final drive vs the Rams ....
