It was Richard Jefferson, Jason Collins and Brandon Armstrong.
The funny story is that Houston couldn't decide whether to draft Brandon Armstrong or Gilbert Areans. They looked at their lineup, saw they already had Steve Francis and Cuttino Mobley, so basically thought that Armstrong would be a better investment that Arenas. So they drafted Armstrong and traded him, Collins and Jefferson for Griffin.
4-5 years down the track, I don't think that was such a good move!
Here's another question; pretty simple if you know...Who drafted Scottie Pippen and with what pick?
elie? or ... oh man .. umm .. mark bryant.. the guy that played for bulls??? oh i dont know.. elie i think went to spurs after the rockets... bryant.. and zan tabak went to raptors.. so its gotta be someone thats a small name
