Despite only three practices, we've seen plenty from the Steelers at training camp and here is what we've learned so far.

The Pittsburgh Steelers have arrived at training camp with a far different team than the one that was blown out in the playoffs in Baltimore in January.

Cam Heyward, Keeanu Benton, and Derrick Harmon are certain roster locks for the Steelers. Yahya Black and Daniel Ekuale feel like locks. But the Steelers kept eight defensive linemen on their initial 53-man roster last year, leaving three spots, give or take, available for the remaining D-linemen on the team.
