The Steelers were happy with what they saw from Kelvin Beachum last season when he came in to play left tackle for Mike Adams, according to Ed Bouchette of the Pittsburgh Post-Gazette.
Barring more of that, the Steelers line should be stable. The only real competition might come at tackle where there are three players and two starting jobs. Mike Adams opened last season at left tackle, starting the first four games before they switched to Beachum.
The Steelers were happy with Beachum, their seventh-round draft choice in 2012 who is undersized but makes good use of technique and leverage. It is conceivable Adams could compete with Beachum at left tackle, but more likely the competition will come between him and Gilbert on the right side.
