mds1 posted:My son and one of his teammates tried the tire drill about a hour ago. Unfortunately, my son decided to do it in his bedroom and now we're missing a 4-foot wide chunk of drywall. His teammate did the drill in the family basement but was not prepared for the rebound and took a Michelin to the nose.
Neither were able to get any MPH readings.
No kidding? I should have used a disclaimer. You need a really solid wall or alternatively a tree. Do it outside.
Never had a problem with a player hit by a rebound ( make sure you hit the wall square at chest height and not on edge) but I had problems with the wrists. To avoid that do not grip the tire with the thumb and hand but just hook it with the index to pinky fingers.
