We have had to replace four starting linemen this year and now we have lost the best OL we had and there have been injuries of one kind or other that has reshaped our OL. not sure what any QB can do behind this OL. Teams need to control the line of scrimmage to win games and we are not in position to do that. Lack of effort is one factor but experience is also a factor. I think most of us feel as though Warriner has done a good job of improving the OL each year but with the injuries his job has become incredibly tough to succeed.
