Donald and Quinn are both superior athletes and can run down plays that most DL have no chance to be a part of. Ogletree and Barron are both supersized safeties with ridiculous chase range. I am concerned with AO's ability to survive the pounding, and he's not a physical tackler like Barron who is much better at delivering hits, but those two guys are going to cover absolutely ridiculous ground. In the front seven you basically have two DL who have LB type athleticism, and two LBs with DB athleticism, it's pretty impressive. I expect to hear a lot about their speed this season.
So yeah, if they can catch a good run of luck on the injury front and get Quinn and Gaines in there, this defense could be really good, like finally finishing top 5 range in scoring type of good. Because who do you block if we have the old Quinn in there with Donald? Man I am praying that's what we get this year, it's been a loooong time coming.
