He said he wanted to play in Charlotte because we were the odds-on favorite for the pick and since we were owned by Jordan he found a connection he thought would be appealing.
I just threw out Chicago because that's his hometown and especially in this day and age of the NBA rarely will any player end up remaining with the organization he was drafted into, especially if it's a smaller market.
Even though it may be true that Davis would have said he was excited to play for any team with the worst record, he also has family in Charlotte and he said his family was excited for him to get to play here. He was excited by that too. So he does have a legit connection here and probably wanted to end up here more based on the situation.
