When you're a high-profile organization that has lately come under scrutiny for its hiring decisions, you can't afford to gamble on high-risk recruits. You need more trusty, worker-bee types in your talent pipeline. And you need to reverse the public's perception of your culture.

That's just one of the talent-evaluation takeaways you can cull from the first round of the 2015 NFL Draft. Here's a full list, loosely sequenced by player selections: 

1. Do your homework and trust your gut. 

Selection: Tampa Bay Buccaneers, Jameis Winston, quarterback, Florida State

Too many hiring stories frame talent evaluation as an either/or proposition, where you've either researched the bejesus out of a candidate or made a decision based purely on an initial feeling. The Bucs clearly went with both their research and their gut when it came to Winston. General manager Jason Licht told the Tampa Tribune he spoke to more than 75 people about the quarterback. 

Likewise, head coach Lovie Smith told the NFL Network that the organization was also aligned around an agreed-upon gut feeling about Winston, whose off-field behavior has landed him in hot water on several occasions.

"You have to trust your instincts," Smith said. "At the same time, we acknowledge he's made some bad decisions. Some young people from time to time do that. I feel like that's the case with Jameis. I've talked to him about everything that's happened with him, and I just don't feel like that's going to be a part of his future." 

2. Take a chance on training a high-potential candidate. 

Selection: Tennessee Titans, Marcus Mariota, quarterback, Oregon

Mariota was ultra-successful in Oregon's idiosyncratic offensive system. The question is whether his proficiency can translate to an NFL system--and whether the Titans organization can coach him through the transition. "The NFL is one of the few industries that finds perfect candidates for their jobs and then makes them change everything," notes the Wall Street Journal's Kevin Clark. 

It won't be easy, but good quarterbacks are hard to find. So Tennessee took the risk on a player who might be a multiyear project. It's the football equivalent of a cutting-edge software implementation: If you pull it off, you'll gain a huge competitive advantage; but pulling it off will take time and resources. 

The good news: Mariota's off-field track record is spotless. And sponsors are embracing his good-boy image. One hour after he was drafted, Beats by Dre featured him in a stylish ad for its headphones. And according to the NFL Network, tweets about Mariota (231,186 in total) had outnumbered those about Winston (191,483) by the time the draft had concluded. 

The Titans don't know what type of quarterback Mariota will become. But they know this much: They're getting a marketable star. 

3. Find the talent with the chip on his shoulder. 

Selection: Oakland Raiders, Amari Cooper, wide receiver, Alabama

NFL teams have always valued players with motivational chips on their shoulders. But in today's game--with more and more players abruptly retiring in their 20s to save their minds and bodies--teams are especially eager to draft players whose enduring love for the game is fueled, in part, by the burning desire to compete and win (and not just cash the check).

Cooper's drive for excellence--stemming from a high school snub--inspired him to surpass expectations at Alabama. After the Raiders picked Cooper, college football writer Bruce Feldman tweeted:

Big believer in Amari Cooper. Terrific drive. Was motivated at #Bama BC a few WRs were ranked higher in recruiting. Now 1st WR in the draft.

Cooper's ambitions don't stop there. He's openly stated the goal of being in the NFL Hall of Fame one day. That's the sort of hunger teams crave. He's far from the only player with a chip on his shoulder in this draft, but you could argue his chip is the largest. 

4. Leverage your cranky high performers by bringing in someone younger and cheaper. 

Selection: New York Jets, Leonard Williams, defensive end, USC

The Jets already had one of the strongest defensive lines in the NFL. The problem? The team's best defensive lineman, Muhammad Wilkerson, has skipped organized activities with the team; since December, he's been asking for a new contract from the Jets, who drafted him in 2011. 

Can Williams, who plays the same position as Wilkerson, be as good as Wilkerson? No one knows. But in the jockeying for leverage that precedes every employer-employee negotiation, the Jets just got a leg up. 

5. Show you value workhorses over show ponies. 

Selections: Cleveland Browns, Danny Shelton, nose tackle, Washington, and Cameron Erving, offensive guard, Florida State

Shelton (339 pounds) and Erving (313) have a combined weight of 652 pounds. 

The Browns two first-round picks in last year's draft--quarterback Johnny Manziel (210) and cornerback Justin Gilbert (202)--have a combined weight of 412 pounds. 

In some ways, that's all you need to know about how the Browns want to assert their identity. They want to be big, tough, and substantive, not glitzy and glamorous. 

Of course, every football team wants to be known as tough. But for the Browns, this battle is particularly pointed. They haven't made the playoffs since 2002. When they've made the NFL spotlight, it's been because of a subtle logo change or an appearance in a Kevin Costner film about the draft. Last year's picks, Manziel and Gilbert, struggled on and off the field. 

With Shelton and Erving, the Browns are literally adding heft and substance to the team. As Terry Pluto notes in The Plain Dealer, the Browns "wisely traded sexy for solid." 

"It was a night that may not inspire anyone to buy season tickets," he writes, "but it could help them win a few more games in the fall."
