How does that fit into this? Others can call you the greatest in a team sport but you can't? Shouldn't that argument extend to other people calling someone the greatest in a team sport as well? After all a certain number 23 gets that nod because of "individual" accolades and accomplishments in a "team" sport.
The sensible one should be the player. THEY (unlike LeBron) realize their success was achieved with the help of others. Ever saw Jordan's video discussing who is the GOAT? He clearly says, it's about the best team and he flaunts his rings and the team record. His challenge to all potential usurpers is simple. Beat the team and then talk shit.
