NBA teams are already paying the guys they want filling up the boxscores $10m+ a yr. With ellis, maggette, jackson, and now morrow, curry, and randolph do you really think the warriors are looking for a scorer? Chances are Ingles has been told we're going to give you minutes, go out there and use your length and skills to disrupt the opposition and make plays on both ends and shoot if your open. Sure he's not shooting well but if points is what they are judging him on he wouldnt still be getting minutes would he?
You are misinformed if you think summer league is just nba teams assembling players and telling them you are all competing for shots so just try and score as many as you can. What happens if a team is looking for a defensive center, do they judge them on how many points they score in a summer league game or how many rebounds blocks and stops they get?
There are many ways to make it in the league but Ingles must start making open shots.
