Sounds so scary...."often with negative results". Don't forget the important stat here. 21 years and two losing seasons. More often than not, his teams come out on top.
What you may call conservative, others may call physically dominating play. Why does he emphasize a running game? Maybe he wants to pound the other team and control the clock? Bill Parcells was highly regarded for this style of play. He had more luck in the post season is the only difference.
Perhaps you are like the other Charger fans who are obviously much happier with Norv Turner's great offensive plays.
Well he's also, the more I look at his long career not just about MartyBall. 6 of his 9 years in CLE he had a top 10 passing attack. It was KC that sealed his "MartyBall" rep but his QB's there were: DeBerg, Krieg, Montana at the end, Bono, Gannon (who played well but Grbac and Bono were the big $$$ FA's) and Grbac. Any wonder he's a running fool? In SDG he was 19, 12, 16, and 16 in passing offense but again you had early Brees for most of those years and oh yes LaDanian Tomlinson so maybe running makes sense.
