DeMarcus Ware and Jared Allen have both claimed that the other could rack up 25 sacks in a single season. While it's nice that the two apparently admire one another, one of them is much more well-positioned to get to 25 sacks.
Allen has been an absolute monster throughout his career and is coming off of a 22-sack season in 2011. Meanwhile, Ware has also been a terror off the edge and finished last season with 19.5 sacks and also had 20 in 2008. Both guys are certainly capable of getting to the quarterback a ton of times, but thanks to the system he's in and the talent around him, Ware has a better chance at getting to 25.
Ware will turn 30 this year and that's the same age Michael Strahan was when he set the current record of 22.5 sacks in a single season. Thanks to his seasons of 19.5 and 20 sacks, he has two of the Top-10 sack totals for a single season since the stat become official in 1982.
Allen recently turned 30 and will be entering his ninth NFL season. While he seems to be peaking right now, the Minnesota Vikings don't have the supporting cast that can help draw attention away from him. Brian Robison had eight sacks in 2011, and fellow defensive end Everson Griffen had four, while defensive tackle Kevin Williams totaled five.
Those three guys have to up their production in 2012 if Allen hopes to avoid constant double teams. Also, Minnesota's horrendous secondary needs to get a whole lot better if they hope to shut down any passing lanes in 2012.
While Ware's supporting cast isn't exactly stacked, Dallas' secondary is what will help him in the sack department. The Cowboys drafted LSU stud cornerback Morris Claiborne in the first round and inked Brandon Carr in free agency. Those two guys are the kind of physical, shutdown corners that can improve a team's pass rush.
Ware also has guys like Marcus Spears, Jay Ratliff, Bruce Carter, Sean Lee and Anthony Spencer joining him in the front seven.
Whole both Allen and Ware are physically capable of reaching the 25 sack mark, I'd put my money on Ware to actually get there.
