There are very few NFL training camps that are run the way that Mike Tomlin and the Pittsburgh Steelers run theirs. Most teams play wrap-up or something less than full contact in an effort to preserve health, but the Steelers are among just a few teams that run full contact. Tomlin says you can’t box without first sparring. They want to get as realistic a look at their players as possible in a practice setting to take any guesswork out of the equation. It is always physical at Saint Vincent College, but veteran DE Cameron Heyward says this year stands above the rest.
