Marcus Gilbert vs. Mike Adams
Before the 2012 NFL draft, second-year man Marcus Gilbert was anointed as the Steelers' starting left tackle in 2012.
But Mike Adams, projected by many to go in the first round of the draft, fell to the Steelers in the second round, and now there will be a training camp battle for the job of protecting Ben Roethlisberger's blind side.
Roethlisberger has been sacked 168 times with Max Starks as the Steelers' primary left tackle since 2008. Starks is now a free agent. If his phone rings, it won't be the Steelers calling.
Gilbert was decent as the Steelers' starting right tackle, but he inherited the left tackle job, more so than winning it.
Bleacher Report's Matt Miller ranked Gilbert a so-so No. 13 among right tackles in his NFL 1,000 series.
Adams (pictured) can't participate in OTAs because school is still in session, but according to Ed Bouchette of the Pittsburgh Post-Gazette, many expect Adams to be the Steelers' starting left tackle when it is all said and done.
Adams might be more naturally built for the position. At 6'7" he's an inch taller than Gilbert. He also has 34-inch arms and 10.875-inch hands, compared to Gilbert's 33.5-inch arms and 9.75-inch hands, according to NFL.com.
Gilbert, however, has the edge in experience, with a year in the NFL's trenches.
