(Eds: Adds details, quotes. With AP Photos.) By PAT GRAHAM AP Sports Writer So Elvis Dumervil doesn't have any sacks through the first two games.
Hardly a big deal this early in the season. Or so the Denver Broncos defensive end thought.
His mom recently called and asked him very matter-of-factly, ''Why don't you have any sacks yet?''
So maybe this was a little bigger deal than he figured.
Dumervil insists his sackless start has more to do with double teams than anything else. Blockers have simply figured out a way to neutralize his patented moves, the ones that led to a league-leading 17 sacks in 2009.
Now, it's up to Dumervil to counter. He's watching tape of sack specialists from around the league, looking for new maneuvers he can incorporate into his pass rush.
''It's a chess match,'' said Dumervil, whose Broncos (1-1) will host Houston (2-0) on Sunday. ''It's all about studying film, knowing what's coming and when it's coming. I've got to get a step ahead of them.''
