Rainey can bring an added dimension to the Steelers offense as well as handle some of the returns for Antonio Brown. He is the sixth running back to get drafted by the Steelers in the past 10 drafts. Here's a look at the others:
Cedric Humes, 2006, seventh round: Broke his neck in an NFL Europe game in 2006 and never played again.
Rashard Mendenhall, 2008, first round: Led the Steelers in rushing for the past three seasons.
Baron Batch, 2011, seventh round: Was impressive in camp before tearing his ACL on Aug. 10.
