Stats don't tell the everything but they do tell something:
25th in the NFL giving up 270 yards per game, not very good, I still compare all Giants Defenses to the 86 Giants, probably unfair
9th in scoring at 20.8 points per game, better than I thought
12 in sacks with 31, very disappointing - Osi and Tuck in particular
2nd in interceptions with 20, Stevie Brown, who would have known
21st in Rushing defense at 123 per game, I believe TC used the word soft
27th against the pass, pathetic
Fewell has a SB ring but the D is not good and under-performing in my opinion.
