Antonio Brown and Le’Veon Bell no longer are with the Steelers, but two former teammates believe quarterback Ben Roethlisberger is the real problem in Pittsburgh.

Former Steelers running back Josh Harris even accused Roethlisberger of intentionally fumbling a ball in a game in 2014 to protest a called play.

“2014 week 17 we were playing the bengals,” Harris tweeted earlier this week. “Todd Haley called a run play with very little time left in the game. Ben wanted to kneel. He rolled his eyes in the huddle. He then purposely fumbles the ball. I had to recover it. At that moment I knew what kinda person he was.”

Harris, who only played one season for the Steelers after he was signed as an undrafted free agent, also tweeted out a video of the play in question. He was responding to a post by another Twitter user who had claimed Roethlisberger is the Steelers’ “real locker room problem.”

“Ben is a great player but he doesn’t try to connect with teammates,” Harris told MMQB.com. “During my time there, I had conversations with vets like, Heath Miller, William Gay, Cam Heyward, Darrius Heyward-Bey, Will Allen, Ike Taylor, Troy Polamalu, Bruce Gradkowski, even James Harrison, but never Ben. Troy made an effort to talk guys. Not Ben though. And it was like that for others too.

“He is close with the O-line and maybe a few guys here and there, but for the most part he stays to himself. During practice when the team would be warming up a lot of times he would be sitting on the water coolers reading the newspapers. So when Ben is critical of players publicly without having a relationship with them, it can rub them the wrong way because they don’t know if it is out of love or what. And when you call out All-Pro guys, that definitely doesn’t sit well with them.”

In the past week, Brown was traded to Oakland and Bell signed with the Jets as a free agent.

Isaac Redman, another former Steelers running back (2009-13), also told MMQB there was a disconnect between Roethlisberger and teammates, particularly when it came to the quarterback “criticizing them publicly,” as he did with Brown late last season.

“It’s going to rub guys the wrong way,” Redman said. “Some stuff should be kept in-house. You come to them, you don’t put it out in public. When you do that, you open yourself up to criticism.”
