One of the more unusual stories to come out of the NFL in the last week is the allegation that Steelers quarterback Ben Roethlisberger fumbled on purpose late in the fourth quarter of a big game in 2014 https://www.thesteelerslockerroom.com/authentic-juju-smith-schuster-jersey , just to spite offensive coordinator Todd Haley.The story sounds crazy, but it comes from a reputable source: The teammate who recovered the fumble, former Steelers running back JoshHarris.However, another former teammate, Bruce Gradkowski, is saying the story is false. Gradkowski was Roethlisberger’s backup at the time and says he remembers the play well and is certain Roethlisberger’s fumble was an honest mistake, not a deliberate one. According to Gradkowski T. J. Watt Jersey , Roethlisberger fumbled because the play had the fullback in the I-formation, when ordinarily the Steelers ran that type of play from an offset I-formation, and Roethlisberger didn’t realize the fullback was right behind him when he turned around to hand the ball off. Gradkowski says the Steelers changed their offensive terminology after that fumble to give the quarterback a reminder that the fullback would be directly behind him.It seems odd that the Steelers would need to change their play calling after Week 17 because their veteran quarterback made such a fundamental mistake like that. Gradkowski’s explanation may be a more charitable explanation than Harris’s, but neither explanation speaks well for Roethlisberger. The Steelers have been a mostly stable team up front in recent years, but they needed to find some depth this offseason.So they’re trying to get the new guys trained in as many spots as possible.Via Chris Adamski of the , rookie tackle Derwin Gray said he’s practiced at every non-center position on the line through OTAs.“I pretty much have played at all four positions since I have been here,” Gray said. “Left tackle Jerome Bettis Jersey White , right tackle, right guard and left guard. It’s all football [regardless of position]. It’s all zone blocking, outside zone, pass protection, that’s all it is.”Gray, their seventh-round pick from Maryland, started 25 games the last three seasons James Conner Jersey White , all at left tackle. But the Steelers are set with starters, largely into the future.With Matt Feiler stepping into the starting lineup at right tackle for Marcus Gilbert last year, and the Steelers extending center Maurkice Pouncey and right guard Ramon Foster, they have starting jobs accounted for the apparent future. Which means picks like 2018 third-rounder Chukwuma Okorafor and Gray and others have to cross-train.
