Everything done while under the Bobcats (as little as it is) has to be incorporated too. I'd say they'll do like they did for the Jets in the NHL. Everything with the original Hornets is still in New Orleans with that franchise, and everything done with the Bobcats here goes with the new Hornets.
That sucks that everything done with the original Hornets would be considered NO history. It was done in Charlotte, by a team named the Hornets. Now that team is back in Charlotte.
