I buy mostly baseball and football sigs.. I always buy sigs on OMLB and Official DUKE NFL footballs.
Now I look at a lot of basketballs and even ones that are UDA are not always Official NBA basketballs?? I see more indoor outdoor balls, wilson, and spalding. Some are official NBA balls but most are not..
Is it normal or more accepted in the basketball market to see signatures on non official NBA balls? Or should it be the norm and expected to see a Jordan and Lebron on Official balls?
