MOBILE, Ala. — One long, hard look at the Ladd-Peebles Stadium bleachers gives you an idea how seriously the NFL takes the Senior Bowl.

You just need your “Where’s Waldo?” skills.

Among those spotted at this week’s practices: Cowboys owner Jerry Jones, Jets coach Rex Ryan, Lions coach Jim Schwartz, Seahawks coach Pete Carroll and a couple general managers.

That doesn’t include the two NFL coaches whose staffs are leading the teams on the field — Leslie Frazier of the Vikings (North, which includes five Boise State Broncos) and Mike Shanahan of the Redskins (South).

In all, the Senior Bowl estimates more than 800 NFL personnel visit Mobile — some of whom haven’t seen any of the prospects in person yet.

The North roster for Saturday’s college football all-star game includes Boise State’s Kellen Moore (quarterback), Doug Martin (tailback), George Iloka (safety), Shea McClellin (defensive end/linebacker) and Billy Winn (defensive tackle).

“If you see me at these practices, I’m usually down on the field,” Jaguars general manager Gene Smith said. “Because I want to feel the player, not just see the player — how they compete, what type of shape they’re in. So that, to me, is a big part of the live exposures. A lot of the things that you don’t see on film, between plays, you get a chance to see on the sideline.”

Eighty-three of the roughly 100 participants in last year’s Senior Bowl were drafted. For the seventh straight year, at least 10 players were taken in the first round (12). And every player at least made it to an NFL training camp.

The Vikings hold 10 picks in this April’s draft. Frazier, who has five of last year’s Senior Bowl participants on his roster, figures he’ll take some of the players he’s coaching this week.

His quarterback, first-round pick Christian Ponder, was the Senior Bowl MVP last year.

“It’s a great situation for us to have a weeklong interview in a somewhat-intimate setting, but one we really can create,” Frazier said.

His approach: Treat the practices and meetings like the ones he runs at home.

“We’re trying to give the players a feel for what a pro practice would be like, to see how they respond,” he said. “The same thing with our meetings. You want to see how guys accept the type of coaching we’re giving. Then you try to determine if they’re going to be a good fit for what we’re doing. If they do, it raises the ante a little bit on the determinations you’re trying to make.”

At the same time, the coaches are aware that they’re not the only ones who want a closer look at these players. Shanahan reminded the prospects to give the scouts and coaches from other teams some of their time between practices and meetings.

“They get a chance to evaluate your play throughout your college career and people want to talk to you here and see what you’re like,” he told them.

“We get to see that a little bit more. We get a little advantage there. But for most of the teams, they just want to get a chance to know the player.”

David Dunn, the agent who represents Moore and Martin, estimates that 80-85 percent of a player’s draft evaluation has been completed by the end of college. The rest gets filled in during all-star games, the NFL Scouting Combine and other workouts.

“It’s the playing that defines these guys,” Dunn said. “You can see Kellen’s vision and decision-making in all the numerous games that he’s played far better than you can in a more artificial environment like the Senior Bowl. That’s not to say the last 15 to 20 percent isn’t significant.”

Just look at Ponder, whose strong Senior Bowl performance vaulted him to the No. 12 pick in the draft and eventually a starting job with the Vikings.

ESPN draft analyst Mel Kiper Jr. said Chargers quarterback Philip Rivers and Ravens quarterback Joe Flacco also made big jumps in Mobile.

“That week can really help you,” he said.

This week, Martin and Iloka have generated a buzz — and Moore’s effortless dissection of the defense in Tuesday’s practice reminded coaches why he’s here, despite his much-maligned measurables. Plus, McClellin is playing out of position at inside linebacker — an opportunity to show the NFL his versatility.

Moore is one of six quarterbacks in town, all of whom are vying for the No. 3 slot in the position rankings, behind consensus No. 1 Andrew Luck and Heisman Trophy winner Robert Griffin III. The other North quarterbacks are Kirk Cousins (Michigan State) and Russell Wilson (Wisconsin). The South features Brandon Weeden (Oklahoma State), Nick Foles (Arizona) and Ryan Lindley (San Diego State).

“We really tried to express to them the urgency of showing in front of 32 different teams,” Frazier said. “It’s something we wanted to make them aware of — this is your opportunity to really shine. All three of them (on the North team) had great college careers. This is the time to really separate yourself and make a statement.”
