I was reading about the beginning of the Charlotte Bobcats (don't ask me why) and it made me wonder about how a team comes to be. Now, on Wikipedia it says they acquired young players such as Gerald Wallace in the expansion draft. Wallace was already drafted a few years prior by the Kings so why was he available for the new Bobcats to draft? Also, it says they made a trade with the Clippers to acquire the #2 overall pick to get Emeka Okafer. Wouldn't they already have a high pick being a new team? And what could they possibly have had to trade for the #2 pick? Basically, I'm just curious how it works when a new team is assembled. What draft pick do they get and what players are available to draft in the expansion draft and what free agents are available to sign?
