I actually disagree wit hall of this.the most disappointing thing to me is that there hasn’t been much improvement anywhere else. The line still stinks and they have one of the worst WR rooms in the league.
I think the OL, while disappointing this year, is poised to be a major strength for the next 5+ seasons and in general think Kahns added some very good young talent with both of his draft classes. One guy got hurt, the other regressed but give it some time and I think his approach to building the team from the lines out and the players he picked to do it will prove to be the best thing about this team over the next few years.
The problem is our best and highest paid players on defense were getting old when the he took over what I considered one of the worst overall rosters in the league. Which I do absoltuely give Tomlin credit, a lot of it, for pulling into the playoffs. I'm just not wired for this to be my goal. I think he has a lot of strategic defencies both in his coaching and hiring of his coaching staff that prove problematic in the playoffs.
This all boils down to me of what you want. You want to be competitive every regular season it's hard to argue against Tomlin. You willing to risk being worse in the regular season for a shot at being better in the post-season I think the team can do better then Tomlin.
