Its not much of a data sample to go by but I came away with some impressions and thoughts.
I'm glad that the Spurs have the rights to Marcus Denmon and that he is stashed overseas where he can only get better.
I'm concerned about Cory Joseph's "re-injury" to his back. Stated as a re-injury, is this going to plague him throughout his career?
Deshaun Thomas likely gets invited to camp, if for no other reason, than the Spurs drafted him. Ideally, I'd like to see him get hooked up with an Asvel contract in France so that the Spurs don't lose him and he can learn to play SF and speak French at the same time, which is something he may need if he wants to play on future Spurs teams.
Hollis Thompson and Dexter Pittman may have shown enough to get invited to camp as longshots but the Spurs often invite players they took note of from other Summer League teams as well, so you never know.
