The OL is a question mark like the rest of the offense. Have no idea how good or how bad they are.
It's tough to spot any trends when all of us fans got a shot at playing OL last year due to all the injuries, plus you had 2-3 rookies starting on any given game day.
I can't stress enough that continuity and coaching matters. Trading your LT, canning your OC, adapting to the no-huddle, then throwing that away when it didn't work, protecting three different quarterbacks, all with different throwing progressions and ability to read the defense and routes, canning your HC mid-season, plus all the injuries...it makes Fred Jackson's achievements last year look like weekly miracles.
Last year was such an epic mess, and this team still won six games. I think that's a sign that the team has talent.
