Who has been the most impressive player to you over the first five weeks of the season?

On the offensive side of the football, it's hard to argue against DeMarco Murray. The running back has been a machine. He's run the football, caught the football and, unfortunately, also fumbled the football. If he can hold on to the football and keep up this pace, he could compete for the NFL’s Most Valuable Player. Murray has been very impressive. Peyton Manning, Aaron Rodgers, J.J. Watt and Le'Veon Bell also come to mind. Other than Murray, Bell has been the league’s top running back. But nobody has been more impressive than Murray, who is one of the biggest reasons Dallas is where it is today.
