I would not throw the baby out with the bath water. I have joked about trading Lamar for a 1st this year and one next, but in all honesty, no way do you trade a hall of fame quarterback in his prime.
We, the fans, do not know what went on inside the team, why he and so many other players did not play as well this year as they have the past several.
Injuries, team politics, who knows. This year, his running was slower, no doubt. But a hammy, a knee, a foot, even a back, all slow you down even when you first get healthy. Get him healthy, fix the line, this offense will hum as it did last year, provided Monken is still here.
