Former five-star RB, Deshaun Watson's backup among Steelers' undrafted free agents

As soon as the 2017 NFL draft wrapped up, the Pittsburgh Steelers got to work on signing undrafted free agents. About an hour after the making the final pick, the team released the names of nine new players:

Rushel Shell, RB, West Virginia: The former five-star running back out of Hopewell (Pennsylvania) High School -- home of NFL great Tony Dorsett -- played one season at Pittsburgh before transferring to West Virginia, where he rushed for 514 yards and five touchdowns in 2016. He has yet to match his enormous prep potential.

Francis Kallon, DE, Georgia Tech: This mammoth 6-foot-5, 300-pounder recorded 15 tackles (three for a loss) as a redshirt senior starter.

Scott Orndoff, TE, Pitt: One of two Pitt free agents to sign with the Steelers and play alongside college buddy James Conner, the team's third-round pick. Orndoff projects mostly as a blocking tight end at the next level.

Nelson Adams, DT, Mississippi State: Adams grew up in Mississippi, played five years of college ball in that state, and now moves to Pittsburgh. Adams collected 80 tackles (seven for loss), four sacks and two blocked kicks for the Bulldogs.

Christian Brown, DT, West Virginia: Draft scouting reports peg the 6-2, 305-pound tackle as solid but unspectacular because of lack of size. Could work his way into the interior line rotation for camp.

Ethan Cooper, G, Indiana (Pa.): The 322-pounder might be the most intriguing UDFA of the bunch after generating NFL interest in the Pennsylvania Scholastic Athletic Conference. Played mostly right tackle as an all-conference performer. Didn't get scholarship offers out of high school due to poor grades and poor physique, according to NFL.com.

Nick Schuessler, QB, Clemson: Schuessler backed up Deshaun Watson at Clemson, where he completed 23-of-33 passes for 334 yards and three touchdowns in 2016. He originally signed with Mississippi State out of Grayson (Georgia) High but transferred, hoping to win the starting job. Watson had other ideas.

Terrish Webb, DB, Pitt: The 5-foot-11 free safety from nearby Clairton, Pennsylvania, started 13 games with 66 tackles and six pass breakups in 2016. Made National Honors Society in high school.

Keith Kelsey, LB, Louisville: Son of Keith Kelsey Sr., who played linebacker for Florida in the 1990s. Kelsey was recruited by former Louisville coach Charlie Strong, who also coached his dad. Was one of Louisville's leading tacklers over three seasons.
