It is the same reason that the Miami fans consider Zo the best C to ever play in South Beach despite considering Shaq.
could be also the case thats Shaq wasn't in his prime anymore at the heat ;)
Wade is the best active Guard. By the time his career ends he will have surpassed Kobe and will be #3 SG All time.
Wade don't have 10 years of playing left, and the decline will come soon. And Kobe in his prime was clearly better. All the other mentioned too, and if he is remembered like Manu in 20-30 years is questionable.
Also his status as current best guards Kobe is still on a pretty close level, Rose playing good, i personally like Paul and probadly i forgot someone but he is for sure a good candidate for this.
James is the best active Player. By the time his career ends he will have surpassed MJ and will be The Best Player in the History.
i would be surprised if he surpass Bird for the best SF less then James ending considered weaker then Durant(who also shouldn't be compared to MJ, Russel, Magic).
