Yup. And all four are fast as ****. Even Mills, who I have seen is definitely more of a bruising, downhill runner, is by no means slow. He moves his *** along at a BRISK clip.
Mills won't jump cut you as much as the other guys, he's gonna cut to your back shoulder and then blast through your attempt to grab him. That "Nebraska Drill" clip, he back shoulders a DL and just blows through the arm tackle and attacks it very vertically.
Please believe that a dude like him running inside zone is going to cause absolute hell for defenses. His presence creates that threat that if you overcommit outside you're getting B-gapped for a huge chunk of yards because he sees a crease and he attacks it with hate in his heart.
I'm more excited about him than I would be 3 more guys who can clock a 100 under 11.0 because of what it opens up for their core package of inside and outside zone. His presence forcing them to keep LBs looking inside is going to create explosive plays for keepers and triples.
