Roy OU Williams in his first years because no player in Cowboys history could light up ball carriers like that and get a rise out of the crowd and his teammates like that. He was a human wrecking ball.
Romo, no other Cowboys QB has ever played the position like that. The man threw more "hold your breath" passes than any other QB.
Favorite all time receiver is Alworth but he didn't play long enough to qualify so Bullet would be the choice there. He had another gear that was so obvious that it would shock defenders the first time they saw it. When he returned punts, ST coaches had to practice different angles for his tacklers or when they got there, Bullet would be long gone.
Tony Dorsett, the best pure RB to ever wear the Star and was a master at setting up blocks and acceleration.
And LA. In the 4Q of games that were being run out by our run offense, the sight of DB's trying to grab turf without it looking like they were doing just that when he would be at the second level. And I never blamed one of them. I think they all had a code for when he pulled and was coming...RHINO!!!!!
But my favorite Cowboy of all time, Roger, throwing jump passes over the middle is one of my most vivid memories of any Cowboys player. Nobody, I mean nobody was doing that as it was a lost art but I guess he thought if Landry is bringing back the shotgun, he could bring back the jump pass. And he was accurate with it because he was unorthodox and didn't have to have his feet planted.
