The Buffalo Bills have an interesting picture at the running back situation. They have two fantastic options in Frank Gore and Devin Singletary, and head coach Sean McDermott still can't give a definite answer on which player will be the team's first option.

According to ESPN's Marcel Louis-Jacques, the 15-year veteran is still the first-choice option for the Bills. Singletary is more than happy to play behind the 36-year-old at the moment.

Moreover, he said that Gore is helping him ease into the NFL life.

“He helped me out a lot,” Singletary said. “At the end of the day, football is football — he let me know that. Don't get too high, don't get too low, just stay in the middle.”

“Just kind of feeding off each other's energy,” Singletary said. “If he makes a good block, I'm trying to get a good block. If he makes a good run, I'm trying to get a good run — that kind of competition.”

Gore had a rough start to his Buffalo career. He had 11 carries but only came up with 20 yards against the New York Jets. Meanwhile, Singletary was able to cover 70 yards with his four rushing attempts. He also had great hands as he caught the ball five times for 28 yards.

Looking at the stats, it's easy to think that Singletary should take the starting spot from the veteran. However, getting him used to the speed of the pro game is more important for McDermott.

Gore may be the starter for now, but it's likely that Singletary will take over starting duties by Week 6. Until then, the two will have a great mentor-student dynamic, helping the future running back be ready to win games.
