Luiz Gohara was long considered to be a pitching prospect with some of the most raw talent in the Braves farm system. Given his high octane fastball and wipeout slider, at the very least he looked like he had a future in the bullpen as a lefty with shutdown stuff. The Braves had higher aspirations for Luiz, however and he showed in the minor leagues that he had real potential as a starting pitcher which increased his ceiling dramatically.
Unfortunately, off the field troubles and injuries derailed him from ever achieving that lofty ceiling in Atlanta.
