Hightower is the popular pick to go to the Steelers in the first round. His leadership ability (a two-time captain at Alabama) and experience in the 3-4 defense makes him a strong candidate to replace James Farrior, who was cut by the Steelers this offseason.
Taking Hightower with the 24th overall pick makes sense for the Steelers. But I don't see this as a slam-dunk choice. The Steelers could look at offensive line and cornerback in the first round as well.
