Dupree was never a big time sack guy in college. 7.5 sacks for the season is the most he ever recorded. I think he's solid ( word used correctly, not applied to Jarvis Jones ) pass rusher, good enough to get some sacks and QB pressures. Dupree has the right build to be tough vs. the run with speed to make plays away from his gap. That's how I see him maturing. The bonus upside will be if he can get a feel and learn coverage in the zone.
I don't see him as a 10+ sack man for the season. I think he'll range between 5-8 sacks while he's here.
Wasn't Watt a 3-4 end? 7 sacks here is good. If your a 4-3 edge rusher as Dupree was, 7.5 as the best effort in 4 years starting is good, not great.
Yes, Ansah only had 4.5 sacks. He only started for one year and had zero sacks in his other college season.
I agree Dupree is an explosive athlete, but he's not going to make a living on his speed rush alone. He has a lot to learn, particularly hand placement, and needs more pass rush moves. Whether he can be a good 3-4 OLB pass rusher is debatable. I don't' see him as the next Porter, Harrison, Greene, Gildon or Brown in terms of sack production at OLB. I think he's a notch below that.
In fact, the 3-4 OLB spot is hybrid these days. Most of the time they are rushing from a 4 man front.
