Friend of mine (D1 stud) from a few years ago. Offered way, way to much money to turn it down right after HS. Stuck it out in the minors for 3 years while trying to hit a big league slider with wood (his words not mine, lol). Didn't work out, but he had a plan. Went back to college and currently teaches. No hard feelings, he knew what he was getting himself into. Simple as that. He took a shot, missed, moved on with his life....... I seriously doubt anybody reading this wouldn't have done the exact same thing if they had his choice to make.
I don't know why, but hearing someone moan/complain about the minors rubs me the wrong way. The biggest issue relates to the Caribbean players. For every one superstar that makes decent money, thousands of others get dropped with no future outside of baseball.
