2015 Pittsburgh Steelers undrafted free agents

The Steelers signed 12 undrafted free agents after Saturday’s draft. Here’s a closer look at each player:

TE Cameron Clear: Clear's 6-foot-6, 277-pound frame allows him to try out tackle if tight end doesn’t work out. The athleticism is there, but an abundance of quality game film, after nine career catches in a pass-frequent offense, is not.

DT Nigel Crawford: Getting the NFL’s attention is difficult when playing for Saint Augustine’s University in the Central Intercollegiate Athletic Association, but the Steelers noticed Crawford’s average of 1.36 tackles for a loss per game last year. Crawford has ideal run-clogging size at 6-4, 307.

DE Dominique Davis: The Liberty defensive lineman from Buffalo, New York, played at 6-5, 285 pounds last year (up from 240 as a freshman), lending possible flexibility to play tackle or end. In 14 games as a senior, Davis had 61 tackles -- 12 for a loss -- and 7.5 sacks.

OG Miles Dieffenbach: Penn State suffered a blow when Dieffenbach, starter of 23 games from 2012-13, tore an ACL last offseason. Dieffenbach didn’t reach the final stages of recovery until late October, so his ability should not be judged on 2014, but his potential moving forward.

OG Reese Dismukes: Dismukes has big-time credentials in the SEC and could be considered a surprise undrafted free agent. He played in or started 50 games for Auburn, becoming an All-American and winning the Rimington Trophy as the nation’s best center. Explosion and athleticism will be question marks at the NFL level.

C B.J. Finney: Quintessential Kansas State guy, using technique and toughness to go from walk-on to 52-game starter for the Big 12 team. Three-time captain has adequate size at 6-4 and 318 pounds, but scouting reports say he has short arms.

QB/WR Tyler Murphy: Has the athleticism to convert to a skill position, leading Boston College to a seven-win season with an ACC-record 1,079 rushing yards from the quarterback position. The Florida Gators transfer completed 120-of-211 passes for 1,526 yards, 11 scores and 10 interceptions. Boston College coaches are high on Murphy's character.

DE Bradon Prate: Prate recorded 62 tackles, 12.5 for a loss, along with 7.5 sacks for Illinois State. Has ideal edge-rush size at 6-4, 265.

OG Collin Rahrig: Showed ability to handle interior rushers in pass protection while at Indiana but is fighting the size battle – he’s listed at 6-2 and 285 pounds, which is too small for an NFL guard. The team captain started 36 games. He’s a smart player who will need to sell Pittsburgh on guard-center versatility.

WR Eli Rogers: Was productive in four seasons at Louisville but never broke out. His highest receiving total for a season was 536 yards, his lowest 454. The 5-foot-10 Rogers likely will compete in the slot. Ability to create separation from defensive backs will be a question.

RB Ross Scheuerman: The 6-foot, 204-pound Scheuerman was often a must-watch player for Lafayette College, producing 3,504 and 31 touchdowns in four seasons, including a resounding 304 yards and three scores in Yankee Stadium for The Rivalry against Lehigh.

OT Kevin Whimpey: Whimpey started 40 games for Utah State over three years, earning All-Mountain West first-team honors in 2014. Led the Aggies with 64 knockdowns. Coach Matt Wells says Whimpey benches nearly 500 pounds. Goodness.
