Well, I'll try to explain it more simply....
The likes of LJ, and as another more obvious example, Shaq, use size and brute force to achieve the same ends that other more 'gifted' 'players' do using skill and finesse.
In that same light, Curry, being one of the most dominant players of the last 10years, were he to be slightly taller and stronger, say for example like LJ, would be more dominant still, owing to his greater SKILL level, of playing the game of basketball.
Rose, in another but similar vein, is/was of a more similar type player to the likes of MJ and Kobe, possessing both high levels of athleticism and skillful finesse. I would say Rose has been the closest answer to the two, with the possible exception of Allen Iverson.
To get back toward the original point, LJ does not help himself by being a complete egomaniac, both on and off the court.
