That's exactly what University of Oklahoma quarterback and Major League Baseball prospect Kyler Murray did when he signed a $4.66 million deal with the Oakland Athletics this month.
The 21-year-old junior will fight for a starting quarterback spot with the No. 3 ranked Sooners
this season before joining the A's in January.
But he's not letting the dollar signs go to his head -- especially when more than 100 of his teammates are living off student-athlete stipends of a few thousand dollars each.
"To me, I'm still broke," Murray told the Chicago Tribune. "I'm not the kind of guy to come up here and blow money."
He added: "They obviously made fun of having money. All that stuff, they make fun of it, but it's all been good. They showed love, supported me through it all, I'm very thankful for that."
Playing for free
By signing a professional contract, Murray lost his eligibility with the Sooners' baseball team, where the outfielder batted .296 with 10 home runs and 10 stolen bases in 51 games last season.
But NCAA rules allow college athletes to play professionally in one sport while maintaining eligibility in others, giving the No. 9 pick in the 2018 MLB draft another year of Division I football.
Murray's unusual situation is an eye-opener in an era where the push to pay college athletes from major programs in some form has gained traction.
As a gifted athlete, Murray will receive little more than a scholarship from the University of Oklahoma, whose football program reaped reported revenues of over $155 million last year
The A's, meanwhile, reportedly received $210 million in revenues last year
, while paying over $83 million
'I'm ready to go'
The fact that Murray, who stands at 5 feet 10 inches tall, is an undersized quarterback for the NFL could have made for an easy decision to commit to baseball.
MLB contracts are generally fully guaranteed for a career that lasts, on average, 5.6 years, according to a recent study.
NFL careers span just 3.3 years on average, according to the NFL Players' Association.
All drafted rookies sign four-year contracts, though guaranteed money is slim outside the first two rounds.
Depending on how his season at Norman, Oklahoma goes, Murray may rethink his commitment to the A's -- and Riley has left the door open for him to return for his senior year.
Should he win the starting quarterback job from Austin Kendall, Murray will succeed last year's Heisman Trophy winner Baker Mayfield, who he shadowed on the Sooners' sideline last season.
Mayfield, the No. 1 pick in the NFL draft, was signed to a four-year $32.7 million deal with the Cleveland Browns.
"I've been doing it my whole life," Murray, who previously played quarterback for a season at Texas A&M, said of competing for the starting spot.
"Obviously, I competed at A&M. Baker, obviously, No. 1 draft pick, we weren't competing, but for me, I showed up every day to compete."
In limited action last season, Murray threw for 359 yards and three touchdowns, while rushing for 142 yards, including a 66-yard breakaway
against West Virginia in his lone start.
"I wouldn't be here right now if I wasn't hungry to play (football)," he added. "I think this is the most anticipated football season I've ever been ready to play for in my life. I'm ready to go."
Murray is represented by Scott Boras, who virtually guaranteed his client's return to the A's. Boras previously negotiated deals for Alex Rodriguez worth an estimated $480 million.
Murray follows the footsteps of other notable two-sport standouts.
Seattle Seahawks Super Bowl MVP Russell Wilson played minor league baseball for the Colorado Rockies, but reportedly returned part of his $200,000 bonus so that he could pursue his NFL career.
Former Heisman Trophy winner Tim Tebow played three NFL seasons before switching sports. He has been in the New York Mets farm system since 2016, but suffered a season-ending injury, breaking his hand in July.
The most famous examples of baseball-football dual athletes in the modern era are Dion Sanders and Bo Jackson.
Jackson, a speedy running back, played four NFL seasons with the Oakland Raiders. He suffered a football-ending injury in a 1991 playoff game, but extended his MLB career to eight seasons.
