My nominees would include:
Bob Lilly
Roger Staubach
Bob Hayes
Deion Sanders
All have an enormous impact at their position.
I love dominant interior linemen. Who doesn't crave what Roger brought to the table? Then there's Deion, who would shut down one side of the field. How about Bullet Bob, the fastest man alive?
If we are talking about bringing back one of these guys to fit on the current squad, I would have to go with Sanders. He is not even close to being my personal favorite amongst the four mentioned above. In fact, he's last on the list.
But what he brought, in his prime, is something I have never seen before or since he played.
Then again, I wonder how the rules today would affect him and other great corners of the past.
Bah, we will never know. So I'll go with the corner.
