Hey, It's That Guy!: Players like Tom Gugliotta, Mike Iuzzolino and Blue Edwards are probably better known for their NBA Jam selves than their real life selves.
Hey, It's That Voice!: The announcer for EA's versions of NBA Jam is none other than Tim Kitzrow, who started out as the announcer of NFL Blitz and other similar sports games by Midway (NHL Hitz and MLB Slugfest).
Screwed by the Lawyers: Due to conflicting player contracts with competing game studios, Acclaim was forced to remove Michael Jordan, Charles Barkley and Shaquille O'Neal from NBA Jam Extreme's player roster. This also got them cut from Midway's Hang Time roster.
Some have also claimed that the three players' filmcontracts that year also kept them from appearing in Extreme. Neither Acclaim nor the film studios confirmed nor denied this.
In 2010, 2K Games gained exclusivity to Michael Jordan's likeliness for NBA 2K11 (Which was his first appearance in a major basketball sim in almost ten years) and onwards, which prevented EA Sports from including him in the 2010 reboot, thus continuing the 20+ year tradition of Jordan being shafted from NBA Jam.
there was rumours that certain cabinets of the original Jam were haunted by Drazen Petrovic's ghost,note Petrovic died in a car crash just before NBA Jam had shipped , software updates later removed him. as the game would randomly call out his name. This actually happened to Jam team themselves, and while it's officially classified as he bug, Mark Turmell pointed out it didn't start happening until after Petrovic had died, and Jam had long been shipped out. Even to this day, original cabinets of Jam will still call out Petrovic's name.
