...from all sports after would he? If lebron could win 2 superbowls for miami as an probowl TE, but retire from all sports after would he?

If LeBron had to leave NBA on the condition he would win 2 NFL superbowls as a dominating TE for the dolphins, would he be content with an NBA / NFL double and would that make him truly the GOAT of American sports? They would say,' well Jordan is better etc , and what about bo Jackson' but I would think 2 championships in each would new huge achievement.. do you?
