"Moving forward, I am firmly and fully committing my life and time to become an National Football League quarterback", he tweeted.
"He's really fun to watch on a football field, and he's going to be fun to watch on a baseball field".

Before Murray announced his decision Billy Beane, Oakland's executive vice president of baseball operations, acknowledged his team might lose the player.

It is very possible - and more than likely at this point - that both Haskins and Murray come off the board before the end of the first round of this year's NFL Draft. The A's will retain his rights if he does choose to return to baseball in the future. You can't blame the league for that, but it does represent how precarious baseball's position on the media map is, as MLB fights the NFL and National Basketball Association for the eyeballs and dollars of fans. This isn't the equivalent of Ken Griffey Jr. or Bryce Harper walking away from the game; Murray is hyper-talented but plenty raw-possibly a star, but not a phenom. Professional football is no cakewalk itself, but it does offer a better landing spot for his particular skills as a highly mobile and strong-armed passer in a league where that's now all the rage.

Part of that is because they have been linked to Murray in the pre-draft process.
There will always be kids who choose baseball, either because they love it the most or because their talents on the diamond outstrip their skills on the gridiron or basketball court.
