The way NFL teams use personnel is different from when I played from 2000 to 2006 as a defensive back. You don't see as many old-school fullbacks with the neck rolls, digging out linebackers in traditional two-back sets. The tight end position? Much more versatility and speed there. Those guys can move. And it leads to positive matchups against linebackers, safeties or even slot corners when the big boys flex from the formation.
That also means the way offenses line up has changed too. Sure, we still see a ton of three-wide receiver sets. But with offenses spreading the field more than ever -- and the passing game becoming more horizontal at times -- the new-school approach has filtered into offensive game plans with personnel, formation and alignment.
