His teams have done very well over the years. He's been better than good.
We'll just have to agree to disagree. Chavis has had defenses that have given up tons of points with future NFL players all over them. The defense gave up a lot of points during the Manning years. And then a ton of points during several seasons of the 2000s. A great defensive coordinator doesn't allow a guy to catch 7 passes after halftime when he caugt 9 in the first half. A great defensive coordinator doesn't give up 62 points to your main competition. Those aren't isolated cases either. The list is fairly long.
See my point???
