The average guaranteed money for picks 1-5 in the MLB draft this year was $7.62M. Every single penny guaranteed whether you go directly to the show, or never make it out of A ball.
The median first round guaranteed money was $4.71M.
Brody Brecht made an ENORMOUS mistake in the long term by playing football. He's finding out that he ain't all that as a pitcher and he wouldn't have made the bigs...but he would've had all that cash had he just elected to try. But alas, he's 18, this is America, and can do what he wants.
40 year old Brody is gonna wish he played baseball, though.
