McGlocklin was best known for his high-arcing "rainbow" jump shot from the wings, in what would now be three-point territory. It was most effective when paired in a two-man play with Jabbar: if the opposing guard fell back to double-team Jabbar, McGlocklin would make them pay from the perimeter; when the guard came out to defend him, he would pass the ball down to Jabbar with only one defender, who under most circumstances was out-matched.
He was selected as one of the Top 50 Basketball Players of the 20th Century in the state of Indiana, as well as being inducted into the Indiana Basketball Hall of Fame, Wisconsin Basketball Coaches Association, and Wisconsin Athletic Hall of Fames.
For the last 25 years, McGlocklin has been a member of the Bucks' television broadcasting team, alongside Jim Paschke.
On the night of his retirement in 1976, Jon founded the MACC Fund, which has become nationally recognized in its fight against childhood cancer and has raised over $45 million towards cancer research. 1
