But, Slump? When you consider a 10 point, 8 rebound game a slump, I think you've found your man. Sign me up for Mullens. Especially in such a shallow league, just 10 teams, it means you will get plenty of talent on WW, so play the "hot" hand.
Just be realistic, Mullens fg % will suck. The man is a 40% fg shooter, so expect that to hurt. Make sure you play that accordingly in your matchup.
