I only watched the interview and I have good feelings about these rookies. Of course I'm not a mind reader or speech analyst, but from what I've heard from them, I like their attitude.
For JR Giddens, I don't see his 'off-court problems' (although little do I know what they are), but he sounds like he's got a rekindled spirit, and he's already got some 'ubuntu' in him.
Walker-only worries are his knees IMO, but he seems confident and that's the first step to full recovery. He also talks about just trying hard, and I really like that especially about younger players (and not just depend on their talent).
Semih Erden- language problem? maybe, but the fact he showed up tells me that he is prepared to work hard and make a roster spot next season and a willing and hard worker.
What are your thoughts?
