This is based on my personal opinion, and I am ranking these players as if they are in their primes. These lists can never be perfect, and I am open to any disagreements down in the comments section.
LeBron James(Lakers)(well duh)
Kevin Love(Cavs)(debated over other players but this is what I ended up doing)
Robin Lopez(Wizards)(slightly older than Westbrook)
Anthony Tolliver(76ers)(slightly older than Dwight)
