That means changes for veteran Willie Colon, who confirmed Wednesday he'll shift from right tackle to the inside.
"I've made the transition to left guard. I like it. It's just a matter of learning the verbiage," Colon told Mike Prisuta of WDVE-FM in Pittsburgh.
Colon is embracing the switch and his size (6-foot-3, 315 pounds) makes him a fit. His one request was ample time to prepare: "My only issue would have been 'Don't move me midway through camp,' " Colon said, before telling Steelers fans to expect frequent pulling in Pittsburgh's man-power blocking scheme.
Colon's first order of business is proving he can finish a season after missing 31 regular-season games since 2009. He tore his triceps last season after missing the entire 2010 campaign with a torn Achilles' tendon. Colon insists he's healthy and ready to contribute to keeping Ben Roethlisberger upright. This time around, he won't be asked to do it alone.
