I doubt that he is a serious immediate consideration. My guess is that these invitees (the non veterans) are possible prospects. If the Spurs still see him as such after camp, they may give him a training regimen to follow. If he shows progress, they may invite him to camp next year. It seems to have worked for Danny Green. It probably worked for Alonzo Gee but the Spurs lost him to Cleveland while deciding on James Anderson.
