Kilgore was rated one of the worst centers in the league before he got hurt. Your other "talented" lineman is a mid round rookie. That's apparently your basis now for "talented" lineman, so we're not really having an unbiased discussion here, are we? We are coming off a season where we had the WORST DEFENSE IN FRANCHISE HISTORY, and then cut some of the best players from it and replaced them with nothing. For you to pretend like we're talented on that side is kind of shocking to me because of the level of homerism required to do so.
You can continue to believe what you want and I won't stop you. I just hope when the team comes out and plays like I know they will you don't fall apart at the realization of what they really are. Just remember that there's an end goal in mind.
Sometimes Is really is as easy as a new coordinator. Look at what Gus Bradley did in Seattle, then Jacksonville, then San Diego. In San Diego, his D literally went from one of the worst to one of the best in a year.
