The key for the OLine is depth. What you saw yesterday was your starting right tackle having to play guard. Your starting right guard having to play center. Your left guard injured and out, so your starting right guard had to play there. Your swingman lineman subbing at right guard. Your backup right tackle having to start.
The Line is a ton better. For at least 10 years, QBs were running for their life. For at least 10 years, the only run game we had was one Adrian Peterson largely manufactured without blocking. Look how bad our run game was yesterday. But this year, a one-dimensional back who runs upright and has only limited speed (Murray) ran for 800 yards and was effective. It is better, and one bad game doesn't make it bad.
Figure out the QB - In my pecking order, it is Case Keenum, Sam Bradford and Teddy Bridgewater. I'd sign Keenum, Franchise Bradford and move on from Bridgewater.
The NFL is a very competitive league. If you have a franchise QB, you compete every year -Brady and Rodgers. If not, it's a dogfight year in and year out.
Defense and a franchise QB. It is the cornerstone. Yesterday, neither showed up....on the road.
