Yes, ultimately what matters is winning and losing. We absolutely needed yesterday's win. A loss would have been crushing. But, you can't look at the performance yesterday and think "Man, that's a playoff football team."
It is fair to say that we need to perform better if we are going to have a chance against the better teams left on our schedule -- which is basically all of them. What really bothers me is that our offensive line is really struggling, and we don't seem to have any answers for it. Benton is doing a good job, but you watch Colledge get flat out abused like he did yesterday, and do you really feel optimistic about blocking the Lions, Bills, Jets, or Broncos defensive lines? Something's gotta be figured out fast.
We saw this last season with the disaster at the tackle position. Your QB is making strides, you see him doing a better job of moving and resetting his feet. You see that when he's got a pocket he can calmly go through four reads and throw a guy open. Problem is, your guards are getting massacred out there like Thanksgiving turkeys. You want to see this kid's play from the pocket improve? Start by giving him a pocket.
There are other problem areas, like the horrible depth at linebacker, Clay's injury, Brian Hartline forgetting how to catch the football, and Ryan Tannehill needing to continue growth as a QB. So you take all of those things together and I think you have some reasons for concern, considering our schedule and the records of other teams in the AFC.
