Kirk Cousins Wouldn’t Mentor Penix in Atlanta. Now He’s Getting $20 Million to Mentor Mendoza in Vegas.

The Raiders signed a quarterback who reportedly refused to help his replacement last year, then plan to draft his replacement this month. History says supportive mentors produce stars 80% of the time. Hostile ones? 25%. Here’s what the data — and every other sport — says about teaching someone to take your job.

Cousins’ Guaranteed Money

On Thursday, the Las Vegas Raiders signed Kirk Cousins to a deal worth up to $172 million over five years, with $20 million guaranteed in 2026. The four-time Pro Bowler, now 37, will almost certainly be joined by the first overall pick in the draft later this month — widely expected to be Indiana quarterback Fernando Mendoza. The plan is clear: Cousins starts, Mendoza learns, and sometime in 2027 or 2028, the torch passes. It’s the same plan Kansas City had with Alex Smith and Patrick Mahomes. There’s just one problem.

Last year in Atlanta, Cousins was asked to do the same thing with Michael Penix Jr., the eighth overall pick. By multiple reports, he refused. An Atlanta source indicated that Cousins’ unwillingness to help Penix was an issue for the Falcons. He didn’t want to teach a young player to take his job. This isn’t unusual — it’s the default setting for most NFL quarterbacks. The unusual ones are the Alex Smiths of the world, who invite the rookie into the film room, walk them through reads, and promise not to undercut them. That’s the exception. Cousins was the rule. The question is whether $20 million in guaranteed money changes the calculus.

“Alex Smith invited Mahomes into his film room and promised not to undercut him. Brett Favre was ‘actually cruel’ to Aaron Rodgers. Kirk Cousins refused to help Penix Jr. The mentor spectrum is wide — and $20 million doesn’t automatically move you to the right end of it.”

Mentoring by the Numbers

Supportive/Professional mentors (n=5): Rookies who became stars: 4 of 5 (80%) Examples: Palmer, Manning, Romo, Mahomes Hostile/Refused mentors (n=4): Rookies who became stars: 1 of 4 (25%) The one star? Aaron Rodgers. A generational outlier. Sat behind veteran Year 1 (n=7): Became stars: 5 of 7 (71%) Started immediately (n=2): Became stars: 0 of 2 (0%) Caveat: Small samples. Selection bias (teams draft QBs higher when they have a clear succession plan). But the pattern is striking: supportive environments produce stars at 3x the rate of hostile ones.

Why Mentoring Works in Every Sport Except the NFL QB Room

NFL QB room: 1 starter. Zero-sum. Helping your backup means accelerating your own obsolescence. MLB rotation: 5 starters coexist. Veterans and rookies pitch on different days. No direct threat. Example: veteran pitchers mentor young arms. NBA: 5+ starters, 8-man rotation. Vets and rookies play simultaneously. LeBron mentors younger teammates while still playing. NHL: Mario Lemieux OWNED the Penguins and still mentored Sidney Crosby. Crosby literally lived in Lemieux's house. The common thread: mentoring works when the veteran's job isn't DIRECTLY threatened by the mentee's success. The QB position is the most zero-sum role in team sports. Only saints or professionals mentor willingly. Alex Smith was a saint. Brett Favre was honest about it. Kirk Cousins was... Kirk Cousins.

Alex Smith and Patrick Mahomes — The Gold Standard

Super Bowls won after Smith’s mentorship

In 2017, the Chiefs drafted Mahomes 10th overall to replace Smith, who was coming off a strong playoff season. Smith could have been bitter. Instead, he invited Mahomes into the film room, walked him through defensive reads, and promised he would never undercut him — a deliberate contrast to what he’d heard about Favre and Rodgers. Mahomes sat for one year, then exploded: 5,000 yards, 50 TDs, MVP in Year 2. Three Super Bowls followed. Smith was traded to Washington and later called it ‘the hardest and most rewarding thing I’ve done.’

The blueprint. Will Cousins follow it?

Times Favre helped Rodgers prepare

When the Packers drafted Rodgers 24th overall in 2005, Favre famously said it wasn’t his job to get the kid ready. Reports described behavior ranging from cold indifference to outright cruelty — excluding Rodgers from team activities, pranking his equipment, making his life miserable. Rodgers sat for three years, became an MVP anyway, and later vowed never to treat Jordan Love the same way. The moral: talent can overcome a toxic mentor. But it doesn’t have to be that hard.

Rodgers succeeded in spite of, not because of

What This Means for the Raiders

“The NFL asks veteran quarterbacks to do something no other sport demands: teach someone to take your job while you’re still doing it. Alex Smith said yes and built a dynasty. Brett Favre said no and built a grudge. Kirk Cousins said no in Atlanta. The Raiders are betting $20 million that Vegas changes the answer.”
