There is a Minnesota Golden Gophers running back who fits much of what the Steelers are said to be looking for in a back-up running back.

The only problem is, he can't run.

RB David Cobb tore a quadriceps muscle during his 40-yard dash at the 2015 NFL Scouting Combine in February. He wasn't expected to light the carpet inside Lucas Oil Stadium on fire, but among a group of running backs that tested relatively slowly compared to past classes, Cobb had the chance to boost his stock a bit higher than his third or fourth round billing.

Perhaps it's just as well, then, he didn't work out at Minnesota's Pro Day Monday in Minneapolis.

Also in attendance is tight end Maxx Williams, another Gophers player who's Combine didn't quite go as well as anticipated. Still, Williams is the top tight end of this class, and may get a look from the Steelers, who hold the 22nd overall pick.

Another name to remember for late round and undrafted prospects is North Dakota State running back John Crockett, who worked out in Minneapolis Monday in front of representatives from a reported 23 NFL teams.

Crockett has good vision, which can compensate for a lack of high-level strength. The Steelers are said to be looking for a power back, but Crockett fits in well with the Steelers' zone scheme, and may be a practice squad candidate.
