Those Guys From Mars
Marshall, Missouri's Ultimate Team
The Windshield Wiper
Picture a triangle, 10 feet on a side. Cones are on two corners, a thrower
and marker on the other corner. Receiver swings back and forth
between the two cones, catching a throw near one cone, throwing it
back, running to the other cone, catching and throwing it back,
repeating this for a couple of minutes. To make this go smoothly, the
marker shouldn't mark hard at all. In fact, he should just stand still,
crouched down slightly, with arms out.

Strengths: Receiver has to stretch to both sides for catches, so the drill
works on quick right and left-handed catches. Thrower has to quickly
throw both forehands and backhands.
