I never said NO improvement. I merely said I don’t expect much improvement. I think the OL will be made up of younger offensive linemen and it is going to take them more than a year to jell into an efficient OL, IMO.
I'm not surprised that your opinion is no improvements next season.
I am not happy with the new OL coach either because if you look at his track record his offensive lines don’t appear good when it comes to preventing sacks. I believe that the OL can develop over the next two to three years and be much better than they have been in recent years but I doubt that Marshall will be the OL coach by the time that improvement takes place.
