NFL Mock Draft 2013: Steelers select Alabama DT Jesse Williams

2012 was disappointing by Pittsburgh Steelers standards. Mike Tomlin's squad failed to make the playoffs for just the second time during his tenure in Pittsburgh.

Though the Steelers had a good year on the defensive side of the ball, CBS Sports' Rob Rang believes that they may look to address that side of the ball further with their first-round pick, 17th overall, in April's upcoming NFL Draft.

Rang thinks the Steelers will select DT Jesse Williams of BCS champion Alabama:

The Steelers have done a nice of job of refurbishing their defensive line with Ziggy Hood and optimism remains high on rookie nose guard Alameda Ta'amu, despite his recent arrest. Rather than gamble on Ta'amu's development, the Steelers might instead choose to develop Williams, an Australian-born defender who has wowed onlookers with his power and upside.

The 6'4, 320-pound Williams began playing football at the age of 14 and is a native of Australia. He was a second-team All-SEC selection.
