For what its worth, I think that KD's sigs are more "wearable" over the last 4 years for the average 'joe" than Lebron's sig. I don't see that changing really if things remain the same meaning they both stay at Nike. Lebron has his fans, followers, and loyalists, but I see KD being every bit as successful, popular, and having his "own" mark and brand if he sticks with swoosh. This second fiddle garbage is really too overstated IMO. Barkley and Pippen and numerous other guys in the 90s coexisted with Jordan and Nike, and I am not sure LBJ is even on Jordan's level. Penny did great and even continues to after the fact with his line, even with the popularity of Jordan and JB.
Let's be clear, Durant is better off with NIKE on a worldwide basis even with Lebron in the mix than he would be on his own and clear #1 with UA. I cannot imagine the thought process being otherwise. I don't think for a moment people will completely shift their allegiance from Nike to UA if KD moves, and if anything it will open the door for someone else and Nike. Just my opinion. Feel free to disagree. Guess we shall see. lastly, I can see many more kids, youth, and younger people flocking towards the KD6s and 7s casually( maybe even for hoops) than the LBJ 10, 11,12 .
