If Murray goes the NFL route then 1 of 2 unacceptable things happened. Either the A’s didn’t do their due dilligence to make sure the guy intended to play baseball, or he severely misled them about his post college intentions.
It’s not super uncommon that a 2 sport athlete could be drafted by MLB and NFL. If anyone remembers, Johnny Manziel was drafted as a shortstop by San Diego, l think. But they used a really low pick because they knew his intention was to play football.
However, before an MLB team burns their number 1 pick on a guy, there are usually conversations held between teams and players to discern what they plan to do. In baseball, players have options. They could go to or stay in college, they could go to Japan, or forego sports altogether and go for whatever career they studied for.
