The Pittsburgh Steelers entered training camp under Mike McCarthy with a different practice structure and a clear goal of reaching September healthier. Cameron Heyward understands the reasoning, but Pittsburgh’s longest-tenured defender is not ready to assume the team can remove live tackling without losing an important part of its evaluation.

Former Steelers head coach Mike Tomlin beats his chest while walking off the field with Aaron Rodgers and Cam Heyward.
McCarthy announced before camp that the Steelers would not tackle to the ground during team periods. His plan is to reduce unnecessary injury risk while teaching tackling through individual drills, controlled teamwork and preseason games. The approach is a significant break from the camp environment Pittsburgh used under Mike Tomlin, who incorporated live tackling periods that were unusual across the NFL.
McCarthy is not eliminating tackling instruction. He believes the staff can create enough physicality through tackling circuits and structured team periods before allowing the preseason to provide full-speed evidence. Heyward trusts that plan, but he also knows drills cannot reproduce every part of a runner fighting to stay upright.
Heyward is not arguing for teammates to spend every practice taking full-speed collisions. He is questioning how the Steelers will identify dependable tacklers when most camp reps end before the defender has to finish the play. Closing space, arriving under control and wrapping through contact are separate skills. A player can look comfortable doing the first two and still fail when a runner refuses to go down.
The concern reaches beyond the starters. Pittsburgh already knows what Heyward, TJ Watt and several established veterans can do in games. Training camp is supposed to provide the same type of evidence for rookies, reserves and players competing for the final spots on the 53-man roster.
Heyward explained his concern during his latest camp comments on his podcast, while making clear that he trusts McCarthy to create another way to test the roster.
“I’ve always been a proponent of, you’ve got to tackle,” Heyward said. “You’ve got to have some physicality that lends itself to showing how you’re going to tackle in the game.”
The problem becomes most visible in the secondary and at linebacker. A defender can be in perfect position at the catch point, but the rep changes if he cannot bring down a tight end, running back or receiver in space. Pittsburgh has dealt with too many plays in recent seasons where correct initial positioning still ended with extra yards.
New defensive coordinator Patrick Graham can teach pursuit angles, leverage and proper form without asking players to finish every collision. The staff can also use thud periods, tackling circuits and controlled goal-line work to increase the physical demand. None of those methods completely recreate a runner fighting through contact with the result of the play still undecided.
The Steelers’ less physical camp places more importance on every preseason snap. Players near the bottom of the roster will have fewer chances to prove they can finish tackles against teammates, so the exhibition games become the clearest live test. One missed open-field tackle could carry more weight when the staff has limited comparable evidence from practice.

McCarthy’s decision also creates a tradeoff between certainty and availability. Live tackling can reveal which players are prepared for regular-season contact, but it also increases the chance of losing someone before the games count. Pittsburgh hired McCarthy to run the program his way, and protecting a veteran-heavy roster through August is a reasonable priority.
Heyward’s concern centers on what the Steelers cannot afford to discover too late. He wants the coaching staff to know which players can complete the most basic defensive responsibility before Week 1 places them in a game that affects the standings.
“We don’t want to get to Week 1 and say, ‘Oh, I think he can do the job,’” Heyward said. “We want to know what we can do and know what we can expect out of guys, from 53 on.”
The focus on all 53 players defines the disagreement. Pittsburgh’s first-team defenders have years of evidence. The questions involve the 48th, 49th and 53rd players who may be forced into larger roles after an injury. A reserve defensive back or linebacker cannot be evaluated only by whether he reaches the correct spot. He has to show he can end the play.
Steelers Must Replace Live Tackling With Real Evidence
McCarthy does not need to reverse his plan to answer Heyward’s concern. He needs a practice structure that makes poor tackling visible before the preseason is over. The Steelers can increase the speed of pursuit drills, create confined-space situations and grade every failed wrap or bad angle even when the ball carrier remains upright.
Graham also has to resist allowing non-contact rules to create false positives. A defender should not receive credit for a stop simply because practice convention ended the rep. Coaches must determine whether the player had the balance, leverage and body position to finish against an opponent who would keep running on Sunday.
The preseason will provide the cleanest answer, but Pittsburgh cannot wait until the final exhibition game to discover a pattern. Young defenders need enough snaps to show how they tackle when fatigued, when the runner changes direction and when the play leaves them alone in space.
Heyward has survived 15 NFL seasons by understanding the difference between looking prepared and being prepared. His concern is not a public rejection of McCarthy’s authority. It is a veteran reminding the new staff that defensive football eventually requires someone to put the runner on the ground.
The Steelers may enter September healthier because they eliminated live tackling. They still need to enter it certain about who can tackle. McCarthy’s camp experiment will be judged by whether Pittsburgh can achieve both.
