Expectations first: anywhere between 7-9 or 9-7. I expect an exciting running game if we can get some much improved blocking and Russell to be consistant, to keep defenses honest. Defense should improve; can't be much more of a letdown as last season, considering the previous couple of years.
Concerns: Receiving. We have a couple of #2 receivers, and no proven threat. This could work to our advantage if they can come out and perform alongside the running game. Both lines need to step up. You cannot perform well on the offensive side of the ball if you have linemen falling on their asses after getting sneezed on, committing false starts every other play, and forgetting their assignments. Solid running backs (Tomlinson, Johnson, etc.) can't be allowed to run free through the d-line, and run circles around the secondary. Main concern is Russell. He's a load of talent, but so was Danny Wuerffal.
With the proper improvements, 2nd in the AFC West.
