Buffalo Bills rookie running back Ray Davis has burst onto the scene over the past few weeks.

He far exceeded expectations in Week 6 while filling in for an injured James Cook, and with a healthy Cook in the lineup in Week 7 Davis still impacted the game.

His play has not only impressed NFL media and fans, but more importantly he has impressed his coworkers at 1 Bills Drive. His teammates have enjoyed his running over the past few weeks so much that they coined a new nickname for the rookie: “The Stallion.”

Bills center Connor McGovern was quoted as saying, “We love when he gets in [the game].” And how could the offensive line not love him? He finishes runs with power and he squeezes the most yardage out of every run. He has maximized his opportunity thus far.

Davis’ coming out party was Week 6 against the New York Jets when he ran the ball 20 times for 97 yards and added three catches for 55 yards. 152 yards from scrimmage in your first extended action in the NFL… not too shabby.

When Cook came back in Week 7, Davis reverted to his supporting role. On just five carries against the Tennessee Titans, he still posted 41 rushing yards and an impressive touchdown:

Davis’ play through seven weeks has the football analytics world taking notice. According to Pro Football Focus, Davis is the highest-graded rookie running back in the NFL with a grade of 76.4. That grade is good enough for 17th among all NFL running backs.

The fourth-rounder out of Kentucky will look to build on his recent play during Week 8’s road trip to face the Seattle Seahawks.
