Von Miller , J.J. Watt and Aldon Smith all should have high sack totals every year, but I particularly like Smith's chances of winning the award in 2013. All three guys play for teams with talented offenses that can get the lead and force opponents to play from behind, thus giving pass rushers more opportunities to get sacks. Smith enjoys the advantage of having a talented rusher opposite him in Ahmad Brooks . Also, when Justin Smith is healthy, Aldon also has an inside rusher the defense must account for.

Meanwhile, Von Miller faces the loss of Elvis Dumervil, which will allow defenses to concentrate on Miller. J.J. Watt is fresh off one of the best years I've ever seen from a defensive lineman. Consequently, opposing teams will do a better job of defending him than they did last year. Look for more creative game planning against No. 99. I think Watt will have another good year, but it is hard for an inside rusher to lead the NFL in sacks, let alone duplicate his 20.5 total from last year.
