The numbers and dominance Al has shown the last couple months are on that superstar level, but there are two things that must be done in order to earn that actual title. One is to show you can produce at that level consistently across a season, and not just have a hot streak over a month or two. The second is as dnbman stated:
Steph Curry didn't get voted into the all star game last year, despite having incredible performances throughout the season. Curry then proceeded to take over the playoffs, going into NBA Jam mode for a couple series. Hence, Superstar Curry is born, and he goes on to lead everyone in all-star votes the next year.
Kyrie Irving hasn't even sniffed the playoffs, therefore, Kyrie is not a superstar. Carry the Cavs into the second round averaging 25 and 10, then he can earn it.
Same with Al - average these 28 and 12 numbers, and take the team 6 or 7 games in the second round against the Heat/Pacers, I think he'll get a lot of buzz next year and should be an all-star easily. Make it to the third round, then I'll get a tattoo of SuperAl on my forehead.
