Polk has been rising quickly over the past year. Polk rushed for nearly 1,500 yards as a senior and displayed many highly sought-after traits for a running back in the NFL.
Polk has ideal size to carry the load for an NFL team. He looks to be more of a compact, agile athlete than he does a power back. Polk is an all-around player who does many things at a high level and is capable of playing within a variety of schemes. He is quick off the ball and a natural runner between the tackles. Polk is patient and has smooth footwork.
Polk displayed elite ability only in his last year at Washington and was a slow developer up to that point. He is a decent blocker in pass protection but can struggle with his technique at times. Polk doesn't have elite speed in the open field.
Future Hall of Famer
A once-in-a-generation type prospect who could change how his position is played
An impact player with the ability/intangibles to become a Pro Bowl player. Expect to start immediately except in a unique situation (i.e. behind a veteran starter).
A quality player who will contribute to the team early on and is expected to develop into a starter. A reliable player who brings value to the position.
A prospect with the ability to make team as a backup/role player. Needs to be a special teams contributor at applicable positions. Players in the high range of this category might have long-term potential.
A player with solid measurables, intangibles, college achievements, or a developing skill that warrants an opportunity in an NFL camp. In the right situation, he could earn a place on a 53-man roster, but most likely will be a practice squad player or a camp body.
