Defending Big Ten champion Penn State is loaded with experience on offense. Quarterback Trace McSorley and running back Saquon Barkley are preseason Heisman Trophy contenders. They'll play behind a veteran offensive line and with a standout tight end in Mike Gesicki.
The one question about that unit going into the spring was at wide receiver. Not necessarily in depth of talent, as the Nittany Lions bring back accomplished players Saeed Blacknail and DaeSean Hamilton at the position. The question was more along the lines of who would become the true No. 1 wideout, someone who could replace the production of Chris Godwin?
The answer to that question might be one of the biggest breakout players in the Big Ten this spring: Juwan Johnson.
The redshirt sophomore created major buzz around the program all spring, earning raves from coaches and teammates and winning Penn State's most improve offensive player award. He showed the public what the fuss was about with seven catches for 81 yards in Saturday's Blue-White game.
Johnson played mainly on special teams last season, though he did start on offense against Purdue. He finished the year with two catches for 70 yards.
"I've been patient the past two years," Johnson told reporters Saturday. "It's time for me to step up and play a role on the team."
It shouldn't come as a surprise that Johnson is ready to make an impact. He's a former ESPN 300 recruit who's listed at an impressive 6-foot-4 and 218 pounds. He could become a top target for McSorley, who often sought out Godwin (59 catches for 982 yards and 11 touchdowns in 2016) during key situations.
"He has just has taken a very mature approach, a very aggressive approach all offseason," Penn State coach James Franklin said. "He's playing with a lot of confidence right now, and I think we all know he's got some special physical abilities. It's all kind of coming together for him right now."
Here's a look at some other breakout players from around the league this spring now that every team has wrapped up its practice sessions until fall camp (in alphabetical order):
Ohio State CB Damon Arnette: Whoever emerges in the secondary for the Buckeyes is a good bet to become a star. Arnette had some struggles as a redshirt freshman last season but performed very well all spring to become the front-runner to start opposite Denzel Ward. Given how much pure talent Ohio State has at the position, that's saying something.
Wisconsin WR Quintez Cephus: The sophomore -- who had four catches for for 94 yards as a true freshman -- turned in some big practices for the Badgers this spring. It was an emotional spring for him after his father was shot and killed. Cephus is in line to replace Robert Wheelwright as the team's No. 2 receiver.
Michigan LB/S Khaleke Hudson: It's unfair to compare Hudson to Jabrill Peppers. But Hudson might well be the guy who replaces Hudson at the Viper position, one where he'll be asked to do many of the same things Peppers excelled at. The early returns have been positive, as Hudson looked like a playmaker during an active spring game performance.
Minnesota S Jacob Huff: The junior has no career starts but has played as a backup the past two seasons. He showed up in a major way this spring at a position of need for the Golden Gophers. "All he does is make plays," head coach P.J. Fleck said of Huff.
Michigan State CB/WR Justin Layne: He made an impact as a true freshman in the Spartans' secondary, even returning an interception for a touchdown. Layne played on offense and defense during the spring game, catching a touchdown pass at receiver. Could he be a true two-way star this fall?
Nebraska slot receiver JD Spielman: The MVP of the scout team offense last year, Spielman looks ready to contribute where it counts this season. He impressed coaches most of the spring and went out and grabbed a 30-yard touchdown among his four catches in the spring game.
Indiana TE Ian Thomas: New offensive coordinator Mike DeBord intends to use the tight ends more than the Hoosiers have in previous seasons, and Thomas should be the biggest beneficiary of that strategy. A standout in junior college, Thomas had only three catches last season but snagged a touchdown in the spring game, a potential sign of things to come.
Iowa RB Toren Young: Akrum Wadley is the No. 1 tailback, but the Hawkeyes like A) spreading the carries around and B) occasionally putting Wadley out in space. Young and Toks Akinribade are both in the mix for work this fall, but it was Young who ran for 96 yards and a touchdown in the spring game. "I liked the energy he ran with and the toughness he ran with, and he's pretty much been doing that all spring," head coach Kirk Ferentz said.
