One thing he can improve on is not running horizontally. Stay vertical.... make your read and go. Sometimes he tends to do go horizontal and while he's got good speed, he's not what anyone would describe as elusive. He's a "see the hole, hit it and go" type of back that seeks out contact, but has good enough speed when he gets in the open field.
The new OL and QB will certainly play a role. It may take some time for them to gel (even with the experience returning) and going up against more stout competition that may take time.
I think he's capable of another 1K season.
