SECONDARY
We were in the middle of the pack in points allowed last year, and were looking good as the season ended. We have added Dowling, Gregory and Wilson (and developmental hopefuls Dennard and Ebner). The secondary should be fine; it may take some time for the secondary to gel.
OFFENSIVE LINE
We certainly aren't as good as last year. Light, Koppen and Waters are all gone.
HOWEVER, Solder was drafted to replace Light and did fine last year, and will be fine after he works with Mankins next to him for for a couple of weeks.
Koppen was declining even at the beginning of last year. Having Wendell at center should be fine. He is probably as good at center as the revolving door in 2011.
The biggest drop-off is from Waters to Connolly. But we know that Connolly is an adequate starter.
I'm fine with our backup interior linemen Thomas and McDonald. I'm also fine with Cannon. He needs a consistent line to work with and he'll be fine. That being said, I would fee much better with the addition with a veteran backup OT to the squad.
The BOTTOM LINE is that Scar has worked with worse lines and has done fine; So has Josh. If the line isn't performing, Josh will adapt the game plan to the OL that we have; he has done so before.
