After graduating from Butler University, Plump played three years for the Phillips 66ers of the National Industrial Basketball League.

Following his professional sports career with Phillips 66, he began working in the life insurance and financial consulting industry.

[1][2] "Plump's Last Shot," a restaurant in the Broad Ripple neighborhood of Indianapolis, Indiana, honors him and is currently run by his son Jonathan.

Bobby Plump and his Milan High School teammates were part of the inspiration behind the 1986 film Hoosiers, starring Gene Hackman as coach of the fictitious Hickory Huskers.

Hickory's star player, Jimmy Chitwood, takes his last-second shot in the championship game from the same spot Plump did in the 1954 state final.
