Lebrons "alpha dog" quality is something Simmons lack. Ingram just doesn't move as well/explosive as Durant. Durant's first step to the basket is exceptional. While Ingram struggles at times to turn the corner
Who does Simmons compare to? Ingram compare to? Then..
Lebron has an "alpha dog" quality?
First I've heard of it. He's been playing for something like 12 years now and I still haven't seen more than 2 or 3 moments where he has actually acted like anything resembling a leader.
Lebron is a softy who lacks leadership skills and who dominates the game because of elite athleticism, and an incredibly versatile skill set. Intangibles certainly have nothing to do with his success.
I honestly think the Lebron comparison is closer to the Odom one.
Odom was a forward had a very skinny frame, and who had excellent ball handling and passing skills by big man standards (which allowed him to play point-forward at times).
Lebron is a SF who has the body of a power forward, and who has elite ball handling and passing skills even by PG standards.
Simmons falls into the latter category much more than he does the former. Odom didn't have ball handling skills or passing skills close to Simmons, and even after 6 or 7 years in the league he still never had the type of body that Simmons has now as a 19 year old.
