I'd definitely put Stephenson, Little and Langer ahead of Richmond Webb, and I'd put Bob Keuchenberg ahead of him too. Look, Richmond Webb was a very good pass blocking LT, but he wasn't particularly strong in the run game, so he's just not in the competition with the other 4 great OL in Dolphin history. And I'll go out on a bit of a limb here and predict that Jake Long will be better than Richmond Webb by the time Jake retires too.
And as I said in at least one of the other top 10 video threads .... the top 3 IMHO just has to be 1. Marino, 2. Csonka, 3. Stephenson. No disprespect to Bob Griese, who was definitely deserving of the Hall of Fame, but Marino was better and arguably the best QB in history. Csonka was the best FB in history without a doubt--and it's not even close. Stephenson was most likely the best C to ever play the game as well ... with the only caveat being that injuries cut short his brilliant career. No other Dolphins can really make a claim to be the best ever at their positions. But if you had an all time NFL team, Csonka would be on every ballot, Stephenson would likely start, and there would be a lot of votes for Marino.
