Will NBA Jam accommodate the new free agent signings the league saw in the past week? Yep. The game released three screens today showing Carlos Boozer, Chris Bosh and, yes, LeBron James, all wearing their new threads.
Does this mean Dwayne Wade is out of the Heat roster? Nope, you can see him in all three screens. And it makes sense: Bosh and James are both post players, Wade's a backcourt guy. So LeBron/Wade is likely the default with Bosh as an alternate or unlockable.
