Just saw a clip of Shaq getting ready and he had one of those old all-star jerseys. Kobe also said they were honoring Jordan with the old 88' jerseys. Here is what it looks like the players will be wearing: nba.com
I don't think they're wearing retro jerseys specifically in honor of Jordan, but rather to be part of the retro fad (doesn't hurt to sell a couple of thousand retro jerseys). The Atlanta theme has been retro from musical performances by Issac Hayes, Gloria Gaynor, etc.
LOVE the jerseys. So much better than everyone wearing their home or away jersey which just leads to mass chaos. And speaking of jerseys, what about what Mariah was wearing!
