I was and still am a huge fan of Neon Deion, but he was not a major Free Agent signing.
Did you know the Raiders I believe it was actually offered more money for Deion? He chose the Cowboys cuz of his buddy Michael Irvin.
Reggie put us over the top, the Cowboys were already a dynasty before Deion got there. Deion was a helluva signing, no doubt, but no where near in the same category as Reggie.
Deion shut down one side of the field - passing. Reggie collapsed the OL and was throwing guys around like rag dolls. Reggie could stop the run and tackle and apply pressure on the QB while making the rest of the team better.
