Dolphins' linebacker Joey Porter needs 2 1/2 sacks to become the team's single-season sack leader. Porter, who could get an invitation to this year's Pro Bowl, has 16 1/2 sacks through the season's first thirteen games. "When you see those pass-rushers that have those kind of numbers start to get up to that 17- or 20-sack deal, you're seeing something pretty special," Dolphins' Coach Tony Sparano said. "I'm glad people are taking notice of it."
