my bet is his going up against defenders with strong+ outside def.
The Team Ratings in the boxscores don't indicate that. He went 7-21 against a team with Awful perimeter defense team rating
(20398141), 3-11 against an Inept (low)
(20398134), and 3-12 against a Pitiful one
(20398119). In all cases my team's Outside Shooting rating was better or about the same. None of the individual players he faced were high salaried; some of them were in the $3000 range.
The guy's played 15 games for me, including cup, scrimmage, and private league, and he's been awful in all of them. There's got to be something more.
