Pfft. Listen to yourselves.
DeMarcus Ware is the best in the game right now, but he's not freaking Lawrence Taylor. 15 sacks is unrealistic, considering the fact that Ware is not just a pass-rusher. He stops the run, he even drops back into coverage against TE's sometimes, because he's that fast.
He's an all-around LB, not just a glorified pass-rusher like Shawne Merriman. That's what makes him so great. He can do everything VERY GOOD.
That being said, I think that he and Greg Ellis will share a majority of the sacks. I also think that Roy Williams will finally start blitzing on occasion, which will take away from Ware's sack total. My prediction is 13 1/2 sacks.
