Here's my ranking of the top SFs in the NBA this season. Again this is largely based off of advanced statistics and is based solely off this season's performance (meaning players like Durant who would normally contend for the top spot on the list ends up sliding due to missing time w/ injury this year).

1 LeBron James........25.8 PPG, 7.3 APG, 5.8 RPG, .582 TS%, 26.20 PER, 7.39 RPM, 12.99 WAR, 17.6 EWA

3 Gordon Hayward....19.6 PPG, 4.2 APG, 4.9 RPG, .572 TS%, 20.60 PER, 5.00 RPM, 10.52 WAR, 11.9 EWA
