Penny Hart, WR, Georgia State: Hart burst onto the Sun Belt Conference scene as a true freshman with 71 receptions, 1,099 yards and eight touchdowns. He'll be the primary target for Georgia State's new quarterback, perhaps Utah transfer Conner Manning.
Hayden Hunt, P, Colorado State: Over the last three seasons, Hunt has raised his average from 41.9 yards per punt to 43.8 to 46.0. He claimed third-team AP All-America honors in 2015.
Shawun Lurry, CB, Northern Illinois: In 2015, Lurry notched a Football Bowl Subdivision-best nine interceptions. He added 43 total tackles and 15 pass breakups.
Nick Mullens, QB, Southern Miss: Mullens was one of 13 quarterbacks to average 300-plus yards per game last season. He threw 38 touchdowns compared to just 12 interceptions. Whether or not he excels without Michael Thomas is a key to watch in 2016.
Austin Rehkow, K/P, Idaho: Though he fell short of a third straight All-American bid as a punter, Rehkow set a school record with 23 made field goals. His career average is 47.2 yards per punt.
Ja'Von Rolland-Jones, DE, Arkansas State: The defensive end followed up a 7.5-sack freshman campaign with 8.5 last year. Overall, Rolland-Jones has 24.5 tackles for loss and six forced fumbles.
