I'm taking Staubach. A lot more mobility than anyone other than Romo.
The reason I'm not taking Aikman is because he was like an expensive sports car - he played great only when every single component (O-line, receivers, running game) etc. was in proper condition. Without those things, he couldn't even get Dallas beyond the wild card round.
I hear this a lot and, while I understand why people say this, I am not really sure it's as accurate as you might think. BTW, I used to share this opinion years ago. However, I have come around to a different point of view.
You must keep in mind that the Offense that Troy played in was very precise. Everything had to be on time, executed exactly right and with minimal deviation. That was the Offense that Troy played in. When Troy was very young, the team was very bad so we never really had an opportunity to see what Troy could do in a more open Offensive scheme. He was pretty much busy running for his life. However, I was able to watch Troy when he was in College and actually see what he was capable of in a less restrictive Offense. I am convinced that Troy could have played in any Offensive scheme in the NFL, had he been drafted by another team. It just so happens that he came to Dallas and was eventually joined with Norv. The scheme limited those abilities in order to accentuate other of his abilities to their fullest potential. Troy was a really good athlete when he came out of UCLA. If you have a chance to watch him play at UCLA under Steve Axman and Terry Donahue, you should really check it out. Most younger posters, who saw Aikman with the Cowboys, either never had opportunity to watch Aikman when he was at UCLA or just forget how athletic he really was. I think he gets short changed there.
