I honestly feel bad for Strahan that Favre took that dive on the record breaking sack. A dominating season that culminated in one of the biggest individual accomplishments a defensive player can achieve and all anyone can think about is Brett Favre pulling the dive. Go back through any defensive players game log and if they have a bunch of sacks at least one or two will be gimmes, it just happens. Strahan was dominating that year and is one of the all time greats, Giant or not.
As to Ware, I think 20 is where I'd set the over/under. I seriously doubt he sets the record, he would have to go on an absolute tear to close out the season. Not completely out of the question with his talent, but 22.5 is just an awful lot.
