(1) How can LeBron be this era's Kobe when Kobe is still playing?
(2) "up there with the Jordans, and the Russells...."
There are multiple Jordans and Russells? Did you mean "....up there with Jordan and Russell?"
Don't write like how Mel Kiper talks. There is nothing more annoying than when talking heads say, "I think they should draft A Ryan Mallett or A Jimmy Clausen," or write a sentence like you did, unnecessarily pluralizing a sentence.
Now, turning to the merits of your argument:
Are you a Red Wings fan? Do you think it hurt Brett Hull's legacy to win a Stanley Cup in Detroit in 2002, "piggybacking" off the work of Steve Yzerman?
Who the hell cares? A title is a title no matter where or when you win it. In 100 years no one will look back and discredit LeBron's NBA title because he played with other good players or on historically good teams.
