Postseason college all-star games aren’t just a vehicle to fill the football void during the week between the NFL’s conference championship games and the Super Bowl.

For those involved, they’re an extended job interview that can determine where or even if a player will be drafted later this spring.

A good week of practice with representatives from every NFL team watching and evaluating can send a prospect’s stock soaring. A bad week could end up costing a round or 2 and a truckload of money.

The game itself isn’t all that important, although a solid performance can never hurt.

Here’s a look at the 5 ACC players who stood out the most leading up to and during last week’s Senior Bowl, which culminated Saturday with a 16-7 victory by the National team against the American squad in Mobile, Ala.

And the one former conference star that didn’t.

5. Payton Wilson, LB, NC State

The Butkus and Bednarik award winner already proved everything he needed to prove to the NFL scouts by staying healthy for the entire season. His performance at the Senior Bowl only reinforced his status as one of the top linebackers in this year’s draft.

In addition to showing off his trademark physicality and instinct to go along with a muscular 6-4, 231-pound frame, Wilson validated the surprising speed that made him a viral sensation when he chased down Notre Dame receiver Chris Tyree from behind during a game in September.

According to several draft analysts on the ground in Mobile, Wilson was the best player on the field at his position during practice. NFL.com draft analyst David Jeremiah ranked him among his 10 biggest winners of the week. He did enough before opting out of Saturday’s game to convince Ian Cummings of Pro Football Network that “if medicals prove not to be a factor, Wilson could be one of the 1st LBs taken.”

4. Jamari Thrash, WR, Louisville

Thrash was a major factor in Louisville’s surprising run to the ACC Championship game. He led the team with 63 catches for 858 yards and 6 touchdowns. But his production dropped off late in the season because of a wrist injury, a swoon that coincided with his team’s year-ending 3-game losing streak.

The 6-1, 185-pound transfer from Georgia State bounced back at the Senior Bowl by reminding the scouts of a big-play ability that helped him produce 14 plays of 15 yards or more for the Cardinals. He caught 2 deep balls for touchdowns in 1-on-1 drills on the 1st day of practice and continued the momentum by showing his versatility throughout the week.

He caught his only target in the game for a 7-yard gain.

“(Thrash) isn’t the fastest or the quickest, but he’s good enough in both areas while also showing really nice hands and a reliable skill for making deep catches over the shoulder,” Trevor Sikkema of Pro Football Focus reported. “On Tuesday, he showcased his vertical abilities, and on Thursday, he showed he could win in the red zone, too. He was one of the most impressive receivers in attendance this week.”

3. Braden Fiske, DT, Florida State

Fiske was already on his way to playing himself into a Day 2 selection after his dominant 9-tackle, 3-sack performance against Louisville in the ACC Championship Game. But his productive week in Mobile, capped by another eye-catching effort in Saturday’s Senior Bowl, may just have sealed the deal.

He finished with 4 tackles, a half sack, 1.5 TFLs and a quarterback hurry. And he did it on the opposite team from the one he worked out with the rest of the week at practice. Fiske became the 1st player in the 75-year history of the all-star classic to switch teams on the day of the game. He was moved from the American team to a National team whose defensive line was depleted because of injuries and opt-outs.

Fiske wasn’t just a star in the game. At a Player of the Week ceremony the day before the game, Fiske was named the top defensive lineman on his team in a vote of opposing offensive linemen.

2. Cedric Gray, LB, North Carolina

Gray’s tackling ability has never been in doubt. He’s averaged 121 per year over the past 3 seasons at UNC. So it’s no surprise that he was around the ball a lot, making plays on his way to a game-high 7 stops for the National team in Saturday’s game.

It was his coverage skills, however, that made the biggest impression and helped raise his draft stock during Senior Bowl week. That was his perceived weakness because of a tendency to get caught flat-footed. But Gray showed the quickness and agility to stay with receivers all week and had 2 impressive pass breakups in the game.

“Gray is a fun, smart linebacker who is not often caught out of place,” observed Nick Farabaugh of SteelersNow. Coming into the week, one of the biggest knocks on him was his experience in zone coverage and it was a feeling-out process. But you could tell that the more he did it, the more comfortable he became. … He kept his aggressive, downhill play style to complement that, too.”

1. Jarvis Brownlee, CB, Louisville

In the estimation of PFF’s Sikkema, Brownlee “might be the biggest riser of any player at any position.” That’s saying something considering the abundance of talent assembled in Mobile last week.

The transfer from Florida State might be small in stature, but he has an unusually long reach. And he knows how to use it to his advantage. He spent most of the week locking down receivers in 1-on-1 drills and carried his strong play into game day.

Not only did he spearhead a National secondary that limited the opposition to only 11 completions and 90 passing yards on 30 attempts, but his interception of former Wake Forest and Notre Dame quarterback Sam Hartman and 32-yard return helped prevent an American score just before halftime.

Brownlee’s performance in Mobile was so impressive that it caught the eye of New York Jets star cornerback Sauce Gardner.

And the one who didn’t …

Tez Walker became a national celebrity for fighting the NCAA and eventually winning his transfer waiver to play for UNC this season. Last week at the Senior Bowl figured to be his next opportunity to shine in the spotlight after leading the Tar Heels with 7 touchdowns and ranking 2nd with 41 catches and 699 yards despite missing the team’s 1st 4 games.

But instead of showcasing his skills and solidifying his draft status, he was a disappointment because of his inconsistent play. Getting open wasn’t the problem. His speed and explosiveness helped him gain separation from his defenders. But when the ball was thrown to him, he had trouble making catches. With far too many drops.

He’s going to have to improve in that area at the upcoming NFL Combine to avoid a further drop on draft day.
