Bill Belichick: Jim, I've admired you for my entire life. When I was head coach of the Cleveland Browns, it was such a blessing to get to know you. ... You were certainly the greatest player. You could've played anything and did. There's nobody other than you that should be the first person in this group. ... I'd put him in there right now on third-and-1.

Cris Collinsworth: If this show was called the NFL 1, we might have the same guest. ... It looks like a dad playing in the backyard with his kids and the kids are wrapped around his legs and you're sort of dragging them and you don't want to hurt the poor little kids. That's what it looked like, like a different sort of being was playing football with some kids out there on the field. ... It didn't matter who he was playing against, he would've been the best in the history of the game.

Belichick: The versatility of this player is just remarkable. He's the only player in the NFL in the 40-40 club: 48 touchdowns receiving, 63 touchdowns rushing. ... He could've played in any era at either spot (RB or WR). ... Nobody catches this guy. I wouldn't call him a power runner but he runs with good power. ... I think he's a little bit underrated.

Collinsworth: The tape is so stunning. It looked like somebody messed up and put a guard in the backfield. ... There were people finding a reason not to go tackle this big guy.

Belichick: Motley was a very unselfish player. He started as atwo-way player. Defensively, he played linebacker. Offensively, he was a blocker as much as he was a runner.

Smith: Work ethic was paramount for him. He was definitely driven. he wanted to work out everybody and anybody. ... His heart was as big as the Grand Canyon.

Belichick: When Barry Sanders gets the ball, everyone's at the point of the attack ... because he could hit every spot on the field. I don't care where he started. That didn't mean anything either. When he got there, you better be ready to tackle.

Collinsworth: Out of my entire experience, the one guy who led the league in "Oooooo", that sound, right? It just comes out of you. I don't know what it is. When you're in an NFL room, and somebody does something that's just off the charts, you start hearing guys go, "Oooooo." It just comes. Barry Sanders led the league in that sound.

Smith: If this guy had not retired, he probably would've been the first 20,000-yard running back in the National Football League.

Collinsworth: Out of all the running backs on the pretty list, it may well be Gale Sayers that struck you first.

Sanders: To me, he seems like one of those guys that we often say is before his time, the kind of athlete he was, the cuts he made. ... It's almost like ballet because it's so graceful the way it catches your eye.

1985 Pro Football Hall of Fame Inductee... Six-time Pro Bowler... 1973 Pro Bowl Player of the Game... Five-time unanimous All-Pro from 1972-1976, topping 1,000 rush yards...

Collinsworth: He was America's hero. He was on all the commercials, he was the guy that was front-and-center for the National Football League, but this was a pretty stunning fall from grace. But I'm going to talk just about football for a minute. His 2,000 yards in a 14-game season is off the charts, and in my mind there was really only one player that you could compare to. Someone that size with that amount of wiggle, with those moves and that speed, and it's Jim Brown.

Belichick: I'm just absolutely flabbergasted at the way you consistently can run the ball for positive yards. I've never seen so many people take so many two-yard gains and turn them into eight-yard plays. ... I'm completely enamored by the way you can set a block and run the football on such a consistent basis.

Brown: This guy's a warrior, man. That attitude, that mental attitude that you must have to be really great, he was the epitome of that. ... He's always got a move, some kind of a move to continue the play.

Belichick: Steve Van Buren was another versatile player. ... This guy was hard to tackle. He ran with a lot of power. These outside plays, he'd start them outside but once there was some daylight he could turn up. ... Good straight-ahead inside runner. Ran with good pad level. He was a mudder. ... As soon as there's room to turn up, he'd turn up. I don't think you'd want to play against Steve Van Buren.

Belichick: It's an incredible honor. It's incredibly flattering. ... We know this is the ultimate team sport, and I've had the great fortune to coach so many great players and have so many great coaches and scouts, it's really an honor to all the people that I've worked with and been able to coach. ... I really believe there is a way to win and you just have to figure it out. ... Fundamentally, it really comes back to, you can go back to a few 100 years B.C., Sun Tzu, The Art of War. Attack weaknesses, utilize strengths and figure out what the strengths are on your team. There are some things you have to protect, find the weaknesses of your opponent and attack. You can't win a war by digging a hole. You have to attack.
