Aldon Smith recorded two sacks in Week 14, giving him 19.5 through 13 games this season and 33.5 since entering the NFL.

Smith has the most sacks in NFL history for his first two seasons.

"Right now, he's No. 1, isn't he?" Justin Smith said. "Nobody has been on a pace for that (many sacks). Right now, he is the guy. You can't rank him with anybody, really."

"He's a young lion, and he's very hungry," Donte Whitner said. "There's no way to stop him. He's like a new-age pass rusher because he's so elusive. You can't really teach a technique to block him. You need two or three guys to really stop him from making an outside move, inside move, spinning."
