Lorbek signed a 3-year deal in 2009 with a buyout after 2 years, meaning the Spurs can bring him over this year with a buyout.
I would assume they wouldn't bother having him included in the deal if they didn't want him; he's already 27, so you think they'd want to bring him over right away if at all.
He's almost 6-11 (I don't know what his standing reach is). He's actually pretty good offensively, less so defensively. He could be very useful though, and he performs on the 'big stage' (Eurobasket) in this video.
http://www.youtube.com/watch?v=AoWW_E5BRBUAs for Richards, here's an interesting comment on him from Xavier Henry right before the Spurs drafted him last year, when reporters asked Henry who the most impressive under-the-radar prospect was.
"The kid from England, Ryan Richards, can really play,” said Henry, the 6-foot-6 shooting guard from Kansas who is expected to go in the first 15 picks. “He showed me a lot of things. He’s a Euro-type of player, but he’s real smart and all of his moves are fast-paced. He can also shoot. That’s something he can do really well. He’s nearly 7 feet and when you have a 7-foot guy that can shoot and plays smart, I think that’s someone who can do some good things in the league."

He'll hopefully get some time as a backup this year if Pop has learned anything.
It might be wise to try to acquire a proven veteran like Pryzbilla (if he's recovered) to be on the safe side, but if not, at least Pop will be forced to play the 'rookies' more. I'm trying not to be too optimistic about them, but I think there is potential there.
