PITTSBURGH — Ben Roethlisberger understands the irony in suggesting the Pittsburgh Steeler practices might be too rough. The $20 million franchise quarterback, after all, is off limits.

Still, a quick scan down his team’s crowded injury list left him wondering if it’s time for the coaching staff to ease up just a little bit.

“I will stand up for the guys up front and running backs, guys who take a pounding every day during a long season,” Roethlisberger said. “The season is super long as it is and very physical. And when you’re doing it over and over and the guys’ shoulders are getting sore, knees start getting sore, and hips and hamstrings and quads and things, and then, they re-occur, you have to take a look at maybe what you’re doing.”

Five weeks into the season, the Steelers already have seen a series of bold-faced names miss time, including right tackle Marcus Gilbert and guard Ramon Foster, the guys who are in charge of keeping Roethlisberger’s jersey clean when it counts. Defensive end Cameron Heyward will miss the first game in his career on Sunday when Pittsburgh (4-1) visits Miami (1-4). Linebacker Ryan Shazier and his sprained MCL are out for a third straight week, and Markus Wheaton’s shoulder continues to bother him.

While Roethlisberger allows that coach Mike Tomlin has to walk a “fine line” about the tenor of practice, he’s also wary of the possible toll it could take over the long term.

“You see those pads on top of lockers being worn all year long,” he said. “Like I said, for me, I can’t complain too much because I’m not the one getting hit. But, I will stand up for the big boys.”

It’s a gesture center Maurkice Pouncey appreciates, even if he’s not completely sure where he stands. Pouncey stressed, “I’m following Ben, baby,” but also understands he gets paid a lot of money to do what the coaching staff asks.

“I’m a lineman,” he said. “I go get it every day and I eat afterward. But nah, it’s cool. We’ve got a physical camp man and it’s paying off now.”

In reality, practices are as gentle as they’ve ever been. The collective bargaining agreement signed in 2011 outlawed “two-a-days” during training camp and limits teams to one fully padded practice over the season’s first 11 weeks and three over the final six. That’s in contrast to early in Tomlin’s tenure.

“Our first year we were hitting every day,” said cornerback William Gay, a rookie when Tomlin took over in 2007. “You can’t get no more than that.”

The Steelers like to “thud up” on Wednesdays, meaning defenders will wrap up ball carriers but don’t take the hit all the way to the ground. On Fridays, the first-team offense faces the first-team defense in the “seven shots” drill from the 2, whichever side getting to four stops or four conversions first claiming bragging rights for the week.
