NFL legend who played into his mid-40s 'alarmed' by Philip Rivers' return, gives QB advice

It's as good a match as the Colts could find since Rivers played for Shane Steichen and the Colts in 2020. So, Rivers is familiar with the offense.

"Because I think that's where he's going to be hurt the most if he has to go with those, you know, third-and-8, third-and-9, third-and-10s, where he might have to hold the football a little bit longer than he wants to. And does he have the escape ability to move around in the pocket like he used to when he played, having been away from it this long?"

Moon admitted he was "alarmed" that Rivers was returning, considering the long layoff.

"He's been away for five years, and even though he's been around the game, he's coached the game, he probably still talks about it with his old offensive coordinator, Shane Steichen, and all those guys. You just don't know how his body is going to react to getting out there every day - the grind of practicing - how his body is going to feel after a week of practice," Moon said. 

"Does he still have those fast-twitch muscles that it takes to go out there and play this game, which has gotten probably a lot faster since he retired from the game five years ago? So, those are the things that concern me as far as his reaction time and how he can get the ball out of his hand quickly enough."
