16. Felipe Vazquez
Of course, Vazquez is nowhere near Hall of Fame contention right now. But based on the way he was playing for the Pirates, there was genuine hope of him being there one day in the future. After becoming a two-time All-Star in successive years, his ceiling looked high.

But then he had to go and ruin it all by being a child abuser. Police arrested him for having sexual relations with a child and for possessing child pornography. Now instead of building a legacy that could one time see him enshrined as an all-time great, he’s going to spend time behind bars.
