My rankings are composed of advanced statistics, xStats, sleepers, busts and lots of projection knowledge. This results in a nicely ordered list of preferred players each year.
Winning your fantasy drafts isn't just about finding super sleepers though. It's also about just finding good value players to fill your team with.
My method for unearthing sleeper pitchers is slightly out of the box but, according to the FantasyPros, I have ended up ranking as the #1 fantasy expert when it comes to ranking starting pitchers over 2016 and 2017.
