Turbo Miller's blazing speed is only part of the story. The Giants rookie RB, who ran a 4.27 at South Carolina Pro Day, has spent the past year proving he can do more than fly past defenders. On the practice squad last year and then in two preseason games, Miller polished his pass-catching, improved route running, and showed patient, gap-aware running in the screen game. Coaches emphasize leveraging his burst with blocks and ball security. With Devin Singletary, Tyrone Tracy Jr., and a productive backfield around him, Miller has a real shot at the 53-man roster, especially if he continues contributing on special teams and in kick/punt coverage. The preseason finale against New England could be the final audition before rosters are locked in next week.
