Lest some forgot, Deano, Marv also had us in the 1988/89 AFC Championship against the Bengals, and we were on our way back to the title game in 1989/90 when this happened...

Couple those two seasons with the subsequent 4 consecutive AFC titles, and that's six straight seasons of near total dominance in the AFC, which Marv crafted on the broken ruins of the Kay Stephenson/Hank Bullough fiasco, and back-to-back 2-14 seasons.
Anyone who calls Marv's coaching accomplishments "mediocre" is either an idiot, or suffers from amnesia.
EDIT: As for Lou, he should have been on The Wall years ago, but to say he would have won at least one Superbowl with Levy's team is saying a lot - like, for starters, that Lou would have stayed with one team for at least 4 years.
