he's one-of-one! TMZSports.com
Tom Brady's had plenty of detractors since his debut in the broadcast booth earlier this year, but Rich Eisen clearly ain't one of them ... he tells TMZ Sports he finds the former QB's mic chops amazing.
The famed sportscaster -- who's worked play-by-play at a few NFL games this season -- gushed over TB12's first foray into color commentating ... saying out at LAX this month Brady is "one-of-one."
Eisen loves the fact that the future Hall of Famer can speak on just about every single issue that crops up in a game -- including injuries, winning, losing and playing into his 40s.
