The three-way race for the Steelers' starting cornerback job opposite Ike Taylor didn't quite live up to its billing this summer.
Curtis Brown, drafted in the third round in 2011, dropped out of contention early in training camp. In what became a two-man race, Cortez Allen, a fourth-rounder in 2011, couldn't beat out incumbent Keenan Lewis.
Of course the Steelers cornerbacks would look better with an improved pass rush, but Lewis is in his fourth year. If he doesn't make significant strides this season, the Steelers might need to look for new cornerbacks to compete with him for a starting job.
This doesn't mean the Steelers should give up on Brown and Allen. There's still plenty of time for them to develop. But good cornerbacks are hard to find, and let's not forget that Ike Taylor is 32.
Gilbert had 59 tackles in 2011, according to CBSSports.com. He was second in the Big 12 with five interceptions and had 15 passes defensed.
He's also returned four kickoffs for touchdowns at Oklahoma State.
