No book in the works yet, so no movie either, but The Blind Side remains under development in Pittsburgh. It will feature Marcus Gilbert or Mike Adams as Ben Roethlisberger's premier bodyguard. Gilbert wants that role, which would come in the form of the Steelers' starting left offensive tackle. Max Starks is gone, and auditions have begun for the job he held the past six seasons. "Obviously, the left side is more important, the quarterback has to have trust in you," Gilbert said. That's where Gilbert said he has practiced the first week of spring drills, with Adams on the right. That could flip-flop at some point this spring because Mike Tomlin might want to look at each player at each position. "One of the things that we learned through the trials of the 2012 season is that both of those young men are capable of playing both spots," Tomlin said last month. "We will use the spring and the summer to sort out where we play those two at." Starks played every down at left tackle last season, but he signed as a free agent with San Diego this week after the Steelers made no attempt to re-sign him. He was their starting left tackle since 2008, moving over from right tackle when Marvel Smith was injured. So Roethlisberger is about to get his third full-time starting left tackle and it looks more and more as if Gilbert will be that man. He said he is more comfortable on the left side, and right tackle seems to fit Adams' style better as a run-blocker. "Right now, I feel really confident with what I have to bring on the left side in protecting Ben's blind side,'' said Gilbert. "I know he's highly confident in me, too." Gilbert opened last season, his second, as the starting right tackle. An ankle injury, though, ended his season after five games. Adams took over until his season ended after six starts because of his own ankle injury. Dr. Robert Anderson of Charlotte, N.C., fixed a torn tendon and reshaped a defect in his foot, Gilbert said. "I have very high arches," Gilbert said. "The doctor changed the structure of my foot.'' Gilbert also changed shoes, wearing them a little higher on the ankle. He also wears an orthosis brace on his right foot for support, and is confident he won't have that problem again. As a left tackle, he will face the best pass rushers the NFL has to offer. The Steelers have switched to a zone-blocking scheme, which Gilbert said he played in college at Florida. No matter what the scheme, the left tackle's primary job is to have Roethlisberger's back.
