Russell showed a lot of potential and improved in many areas.
He only had 8 interceptions, which is excellent for a starter in the NFL. He made many nice throws, and showed mobility and awareness on the field. He helped lead big upsets over Denver, Jets, Bucs, and Texans.
But he has a lot to work on. He only completed 53% of his passes, only threw 13 TD's, and only 2,400 yards. His QB rating was a mediocre 77.3.
He needs more talent around him though, McFadden and Walker were poor, he did not really have a go-to guy, that would really help him.
