I think RW is the most athletic player in the NBA. Lebron is bigger, stronger, and with better basketball skills. Why is that wrong? Russ is def quicker, more agile, more explosive etc.
RW is like a cornerback in the nfl, the position widely considered to be the most athletic in the NFL (some WRs and RBs are close). Lebron is like a tall tight end with all time skills. Why is this a problematic delineation for you,
Because russ isn't more explosive, Lebron's vertical is significantly higher. Russ' max vert is like 36.5. LeBron's is probably around 44. Watch 07-10 LeBron, he was unstoppable in transitions and throwing down thunderous dunks were while tanking through defenders were a natural finish for him. Also Lebron has much better body control at that mass and is much stronger. The difference in strength is far greater than the difference in speed. Add all this up, and you have that LeBron is orders of magnitude better at finishing at the rim and finishing through contact, again probably speaking to his superior strength and body control. To sum it up, basically LeBron has 5 inches and 70+ pounds on him and still isn't much slower than Russ and is probably more explosive. Then you add in the difference in strength and it's not a contest. LeBron could guard and stay in front a lot of point guards, he's that quick. He shut down Parker many times, who is among the quickest there is. DRose got destroyed in the 2011 eastern conference finals with LeBron guarding him. Russ would get mauled guarding any forward. I will say that Russ has an incredible ability to play full speed all the time which is awesome and why he's so good and can contribute in so many years, but LeBron is basically the king of that too.
I like looking at finishing ability as a great indication of athletic ability for a basketball player. It combines strength, explosiveness, and body control. Russ isn't that good as a finisher compared to some other guys. And it makes sense, because he's one of the best there is at getting by the defender with his first step quickness but he's a little overrated in those other areas. A guy like Eric Bledsoe is a better finisher than Westbrook. Meanwhile, LeBron finishes at the rim almost as well as Shaq did...think about that.
Anyways, I took this really off topic, back to tennis!
