MOBILE, Ala. -- From William & Mary defensive back DeAndre Houston-Carson to Southeast Missouri State wide receiver Paul McRoberts and Harvard offensive tackle Cole Toner, small-school standouts are finally on a level playing field with their FBS counterparts.

This week at the Senior Bowl they'll be lining up against guys who played at programs like Alabama and Ohio State all week, with pro coaches, scouts and executives watching closely.

McRoberts is the first Southeast player to make it to the Senior Bowl. Coming from a small-school program, he got a few recruiting letters but no scholarship offers from bigger colleges.

"Me not playing against anybody, they didn't want to take a chance on me," McRoberts said. "That's kind of how I was my whole life."

Former North Dakota State star Carson Wentz is the most prominent of a number of FCS products trying to make an impression on NFL teams throughout this week at the Senior Bowl, and he echoes McRoberts' sentiment.

"I think a lot of the small-school guys come in here with a little chip on their shoulder, something to prove," Wentz said. It's "just exciting to finally get out there and face these guys."

The 6-foot-5, 233-pound Wentz might be the top prospect at the Senior Bowl after returning from a broken wrist to lead North Dakota State to its fifth straight national title. Those NFL executives who couldn't make the trek to North Dakota to check out Wentz in college are now getting a close-up view of the player in the mix to be the first quarterback drafted.

Bison teammate offensive lineman Joe Haeg is also trying to show NFL teams ahead of Saturday's game that he can play at that level.

Wentz is vying with California's Jared Goff and Memphis's Paxton Lynch to be the first quarterback selected. He returned from a broken right wrist, sustained on Oct. 17, to lead North Dakota State to a win over Jacksonville State in the championship game.

Wentz isn't trying to carve a reputation among NFL types but live up to it.

Southeast Missouri State wide receiver Paul McRoberts runs through drills during Wednesday's practice.

"Yes, he was scouted in the fall but Fargo, North Dakota is a tough place to get to," said Senior Bowl executive director Phil Savage, a former Cleveland general manager. "There were probably a handful of (general managers) that made it out there.

"But to be on this stage in front of this many people, I mean this can be almost a coming out party for him: OK, this is who Carson Wentz is, this isn't just a rumor or hearsay or talk."

The other guys from FCS schools face similar challenges, even if they're not being scrutinized quite so closely as a potential first-round quarterback.

Some were undersized or late bloomers who were barely recruited by major colleges or not at all. Wentz grew from a 5-8, 125-pound beanpole as a high school freshman in Bismarck, North Dakota and didn't play quarterback as a junior because of an injury.

"In North Dakota, it's hard to get found in general, let alone missing a junior year," Wentz said. "I came in my senior year at 6-5 and 200 pounds and kind of came out of nowhere."

Teammate Haeg was only recruited by Division II schools, but opted to walk on at North Dakota State. He's packed on about 80 pounds since his freshman year and gone from not being able to bench-press 225 pounds to lifting 380.

"I would definitely say there's a lot of people that kind of look down on FCS players because obviously there's a lot of great players at the FBS level," Haeg said. "But also there's a lot of great players that are overlooked at the FCS level.

"When we get on the field, it doesn't matter where you're from. We're all on the same practice field. We're all out there competing."

Dallas Cowboys coach Jason Garrett, who's leading the North team, said seeing how FCS players fare against bigger-school products is part of the evaluation process.

"Obviously those guys have had a lot of success or they wouldn't be here in this game, but seeing them compete against guys from the programs at the highest level is important," Garrett said.

If there's any shortage of confidence from Wentz and his FCS counterparts, it's not evident off the field.

"The biggest question mark obviously is going to be, can he play at this speed, can he play against this talent?" Wentz said. "I think I'm going to prove that. By the end of the week everyone's going to no longer question that, and I'm excited to prove it."

The Senior Bowl will kick off at 1:30 p.m. Saturday at Ladd-Peebles Stadium in Mobile, Alabama. It will be televised on the NFL Network.
