I have put some thought into what a nice 2-pk combo would be if there was a special series called Dynamic Duo. It would be a 2-pk set with a QB & RB . Here is a few that i have thought of:
1. Terry Bradshaw & Franco Harris
2. Roger Staubach & Tony Dorsett
3. Joe Montana & Roger Craig
4. Joe Theismann & John Riggins
5. Troy Aikman & Emmitt Smith
6. Jim McMahon & Walter Payton
