I have no issue with extending him. I am quite happy, as Ive said before, with 350+ yards of offense, whether that is 250 passing and 100 running, visa versa, so long as it is compelling, competitive, and yes, wins would be nice.
My issue is and has been even when Joe was the qb; provide the right team around him.
They failed with Joe, a pocket passer, they did not get him a good pass blocking line.
Lamar has a good enough line, minus a player or two in the middle.
Neither he nor Joe has the receivers or they didnt/ don't have passing scheme to be successful consistently.
Joe had the same issue; receivers running routes on top of or into each other. Receivers not able to read coverage properly on option routes.
So clearly the issue is 1) coaching & or 2) scouting maybe even 3) front office in selecting receivers.
Pay Lamar, but get him receivers or coaching to help the passing game.
11 + wins is nice but as we have seen over the course of NFL history, the post season is a different animal, you have to be able to adjust to either run when they shut down your pass first offense, or throw when they shut down your run first offense.
There is a very good nucleus on this team, offense, defense, special teams. Good enough to win a super bowl with the right players to complement them; don't waste the next 3-5 years.
