Gilmore spent his better days in the ABA where he averged 22,1 ppg,17,2 RPG in his ABA career.He transformed his game well to the NBA,has godo stats,overall acomplishments and double,should be a Hall Of Famer.

--------------------------------------…
Kareem Abdul Jabbar-In his days in the 70's he won a ring with the cllutch sky hoop that he hit,ROY,DPOY,4x MVP,2 scoring titles,1 rebounding titles,3 blocking titles..................................… 70's acomplishments.This more more individual,the team success was better later
--------------------------------------…
Dr J also spent his better days in the ABA but his NBA career is terrific.He's the legend of the hang time,best magacian with the ball,superb dunker,good defender and rebounder.He won NBA MVP and ring but he could have been better if he had to pla ymore in the NBA.Overall,great game and acomplishments
--------------------------------------…
Pistol Pete,best showman,greta scorer and passer.His NCAA acomplishments are great and his NBA's as well
--------------------------------------…
Walt Fraizers.best PG of the 70's,arguably best defensive PG adn one of the best perimter defender ever.He was a scorer,rebounder adn defender.Not a passing magacian with the ball but good overall player.He's the one or the only player under 6'4 as a PG to have over 20 rebounds in a game and he's aslo the best stealer.He just stole the ball from West and hit the lay up which gave the Knicks a ring
--------------------------------------…
Nate Thurmond-Altrough his better yeasrs were in the 60s,he was still putting great numbers for the teams he had played,still in shppe and back in 19764 with his best game in his career when he had quadruple,he become the first player ever to win a record a quadrupke double
Nice question
