PITTSBURGH (AP) — New Pittsburgh Steelers wide receiver DK Metcalf is quickly making an impression. Metcalf nearly chased down safety Minkah Fitzpatrick on an interception return during the first day of minicamp. The play echoed Metcalf’s memorable 90-yard sprint to tackle Arizona’s Budda Baker five years ago. Metcalf says it doesn’t matter this it was only practice, running after a defender who gets his hands on the ball is part of the job. Metcalf is the unquestioned leader of Pittsburgh’s mostly young wide receiver group. The 27-year-old says he plans to lead by example but also considers himself an “open book” to more inexperienced players such as Calvin Austin III and Roman Wilson.
