Our 5 techs are Green, Jackson, and Collier.
Our Leo's are Mayowa, Taylor, and Robinson with Green having enough ability to play Leo against run heavy teams.
And yes, it's all about strong side vs weak side in base defense. It's not RDE and LDE like in Madden or older, simplistic football. In pure pass rush situations, it's a bit of a different story. Irvin and Mayowa, like Avril, are more comfortable and more effective rushing from the left side and so they do so when they don't have to worry about run defense responsibilities. Taylor and Robinson, on tape, show that they can rush from either side. It sounds as though Irvin will be back to playing SLB on base downs and rush end on pass downs.
Speaking of which, I'd like to point out that Taylor is every bit the athlete that Clowney is (4.5, great vert, etc), and actually looks better at rounding a corner with power and leverage with a clearly superior center of gravity and agility than Clowney. If you want a comp for Robinson, it's definitely Clem, except Robinson is a prospect that's farther along and also a better athlete than Clem. Clem was only 240 coming out of college and it took him quite a few years to bulk up to 260 so that anyone would even consider giving him a measure of real playing time. However, Robinson plays with that very same heavy handed, aggressive playing style with a lot of angry pop.
The Hawks have already upgraded the pass rush, IMO. However, DT is much more of a severe need right now. We have basically two DTs with any measure of experience (although Jackson plays some 3T as well) and our run defense was really pretty poor last year. It sounds like it will likely be Snacks that they are pursuing and, as unpopular as it may be, I will be happy if they get Snacks in the house rather than Clowney, to more holistically complete the line. I'm aware of Snacks' fall off last year, but reading into it further shed some light on the situation in Detroit.
