I don't have a real difficult time picking the Top 10 Cowboys of all time, until I get to the last 3 or so. I do have a hard time rating them from 1 to 10 because it's so hard to rank players that play different positions. OL don't get the stats of a RB, QB, or WR. At any rate, below is my ATTEMPT to rank the top 10 Cowboy PLAYERS. I'm not going to include coaches, owners, etc. Everyone knows Landry would be # 1 if you did include these guys.
1) Roger Staubach
2) Emmitt Smith
3) Bob Lilly
4) Troy Aikman
5) Michael Irvin
6) Tony Dorsett
7) Randy White
8) Larry Allen
9) Rayfield Wright
10) Mel Renfro
Some of the others I considered, in no particular order, include Chuck Howley, Drew Pearson, Harvey Martin, Darren Woodson, Don Meredith, Ed Jones, Cliff Harris, Charlie Waters, Bob Hayes, etc.
There are two players that I think would've been definitely included in the Top 10 if certain circumstances hadn't arisen: Erik Williams had he not been involved in the car crash. He was never the same. Charles Haley if he had played more years for the Boys and if his back had not become an issue late in his career.
There's one current Cowboy that will break into the Top 10 if his career continues the way it has gone thus far. I'm sure to no one's surprise the player I'm talking about is Ware.
Of my Top 10 listed above, I don't see how anybody could leave out Staubach, Emmitt Smith, Troy Aikman, Bob Lilly, Tony Dorsett, Michael Irvin, Randy White, or Larry Allen. To me, that's 8 players that should be a lock in any list that anybody could put together. That really only leaves two spots to argue. Just my take.
