Glenn Roberts was an American National Basketball League player. In college basketball, Roberts was one of the first players to put the "jump shot" to practical use.

In basketball, a player may attempt to score a basket by leaping straight into the air, the elbow of the shooting hand cocked, ball in hand above the head, and launching the ball in a high arc towards the basket for a jump shot. Although early critics thought the leap might lead to indecision in the air, the jump shot replaced the earlier, less quickly released set shot, and eventually transformed the game because it is the easiest shot to make from a distance and more difficult for a defender to block. Variations on the simple jump shot include the "turnaround jumper" ; the "fadeaway" ; and the "leaning jumper". With the "hook shot," a player is turned sideways with the shooting arm away from the basket outstretched so that with a sweep he can launch the ball over his head. Since a defender must leap to block a jumper, the shooter may use a pump fake to get the defender in the air at the wrong time and so have a clear shot. If the shooter leaps into the defender, a foul is called on the defensive player, whereas the shooter is awarded two or three free throws according to the value of a missed attempt, or a single free throw.
