Haha, Brady as a color commentator? Mr. Personality himself? He would be a perfect fit with Cris Collinsworth and Troy Aikman. Put all three on one game each week so week can miss hearing them all at once.
Networks want the name value. It's not about whether they are funny or can explain defenses, the networks just want the guy with the marquee name. That's how Joe Namath, O.J. Simpson and others got commentary jobs.
The worst I ever saw was when CBS hired Johnny Unitas. He spoke in a bland, monotone voice, had nothing important to say, just seemed like some bumpkin who pulled up a chair in the booth and was handed a mic. But he was Johnny U.!! That's all CBS cared.
Brady has done radio segments for years with Westwood One in their Monday Night Football broadcasts which tells me he at least wants that iron in the fire but, frankly, I'm hoping he can find something more useful to do now.
