For others that may not be familiar with NCAA rules, an kicking tee is NOT required during a place kick on a free kick. (A tee is not allowed at all on a place kick from scrimmage, for NCAA games). If Team A brings a kicking tee onto the field on a free kick, the ball must be touching the tee when the ball is kicked for the kick to be legal. It need not be on top of the tee. The ball may simply be on the ground, but leaning on, or otherwise just touching the tee.
This is an example of not writing the rule as thoroughly as they could have. Although alternate scenarios are completely impractical, and are not likely to occur, there is no rule requirement for the tee to be on the ground. The one scenario that would be physically plausible, but of no tactical use that I can see, would be to place the ball on the ground, and rest the tee on top of the ball. Technically complies with the rule, but, would not seem to be of any value, unless the tee gets kicked and a Team B player has take an evasive path keep from stepping on it. But, it could happen.
My opinion doesn’t count, but, I don’t think placing the tee on top the ball should be legal. I wish they would have said that the tee must be resting on the ground and the ball must be in contact with the tee when the ball is kicked.
