That doesn't refute my point. Without BB, the Giants never beat Kelly in 1990. That was BB's #1 defense. Same in 1986 with BB's top defense (#2 pass #2 run). You could say that Parcells lucked into having LT on his roster too. But it was BB who brought out his best and it was the Giants defenses that won them those championships (as defense 'always' does).
Seriously, I do give Parcells credit, but he was never a champ without BB.
