After focusing on the lines with their first three pre-draft visits, the Detroit Lions have moved to a skill position for visit No. 4 of 30, bringing Indiana running back Tevin Coleman into the facility Thursday morning.

Coleman is an intriguing prospect after leaving the Hoosiers early. The 21-year-old was an explosive back throughout his three years in Bloomington, Indiana, with 452 carries for 3,219 yards and 28 rushing touchdowns. He can catch passes out of the backfield, too, with 54 career receptions for 383 yards and no touchdowns. Interesting small fact: His middle name is Ford, which means nothing except the Lions are owned by the Ford family.

Coleman measured at 5-foot-11 and 206 pounds, with 32-inch arms and 8 5/8-inch hands. He had 22 reps on the bench press at the NFL combine. He is rated as the No. 4 running back prospect and No. 51 overall prospect by ESPN.com/Scouts Inc. His scouting profile lists him as above average in competitiveness, vision/patience and agility/acceleration, with average in power/balance and in the passing game.

For more on Coleman, I reached out to colleague Adam Rittenberg, who covers college football for ESPN, for a scouting report:

"Strengths: Doak Walker Award winner Melvin Gordon played for a better Big Ten team, but Coleman often showed just as much or more explosiveness, particularly in the open field. He recorded four 200-yard rushing performances, three against Big Ten opponents, and had a career-high 307 rush yards against Rutgers. Coleman is a big-play machine and shows both power and elusiveness between the tackles. He ran behind an underrated Hoosiers line but produced at an extremely high level despite playing alongside a freshman quarterback (Zander Diamont) who no one expected to play going into the season. His yards-per-carry average (7.5) obviously jumps also, but he also rarely lost yardage (just 26 yards for the season).

"Weaknesses: The only potential knock on Coleman is durability at the NFL level. He has good size but doesn't fit the power-back mold. He missed the final three games in 2013 with an ankle injury. Toughness isn't a question, though, as Coleman played the second half of the season with a broken toe."
