Concerning DJ - There is something to be said for a guy who knows his role and accepts it. He is never going to look good as a featured player on a team, even a D-league or summer league team. However, he has the toughness to play hard a few minutes here and there when called upon. A lot of guys can't sit on the bench for weeks then contribute on the spot, even if all he contributes is physical defense. It's the difference between building a fantasy team and a real team.
When we look at free agents in summer league, we have to look at who plays good enough defense to get in the game and who can be effective without plays being run for him, namely offensive rebounds and wide open kick out jumpers.
