In case you are wondering the money difference.

While the two-sport star reportedly is expected to enter the NFL draft, he already has put pen to paper on a $4.66 million signing bonus with the Oakland A’s. Murray reportedly would have to give back most of the money the A's gave him if he were to play professionally in the NFL instead. https://www.nbcsports.com/bayarea/athle ... l-football
Some have argued that the guaranteed money he’s already agreed to with Oakland would be enough to convince him to stick with baseball and report to MLB spring training in February as the A’s hope.
However, the Oklahoma QB wouldn’t necessarily lose guaranteed money if he chooses football.
In fact, if Murray believes he’ll be a first-round pick in April’s NFL draft -- and there’s reason to believe he could go as high as No. 1 overall -- Murray would earn more money from his NFL signing bonus than the $4.66 million he’s assured with the A’s.
Per Spotrac, first-round picks in the 2018 NFL draft received signing bonuses ranging from $4.97 million (No. 32 pick Lamar Jackson) to $21.85 million (No. 1 pick Baker Mayfield).
So even if Murray was the last pick in the first round, he actually would bank more guaranteed money than he currently has with the A’s.
When considering his future earning potential, that’s when it gets tricky. If Murray turns into a star quarterback, or even a serviceable one, he’ll be heavily compensated for the rest of his career (see: Bay Area quarterbacks Jimmy Garoppolo and Derek Carr, who both signed contracts worth more than $70 million in guaranteed money, per Spotrac).
But since NFL contracts aren’t fully guaranteed, Murray could risk leaving lots of cash on the table if he were to be seriously injured or if he didn’t perform up to expectations.
Conversely, if Murray decides to stick with baseball, he keeps the $4.66 million up front … but then has to wait until he makes the major leagues to make more significant money.
Once Murray makes the majors, he then would have to wait another six-plus years to hit free agency before a monster eight- or nine-figure contract could be waiting for him.
