In sports history, you remember players who win. This is why Troy Aikman and Roger Staubach hold a special place in Dallas Cowboys history despite Danny White and Tony Romo having better stats. Aikman and Staubach have the most important numbers in that they have three and two Super Bowl wins as starting quarterbacks.
Dak Prescott is about to decide to have a Tony Romo career or the potential for a Troy Aikman career (remember potential). It certainly seems like he is intent in following his mentor by choosing to maximize the value of his next contract.
