I was not aware that they could not use tees for place-kicks in college any more. Are you sure about that?

Only on the kickoff like in the NFL. The problem is that they still use a tee in high school; at least they do here in Mississippi.

We use tees here in Louisiana for All Place kicks as well!!! I coach a kid who can hit from 50 yards off the tee ( and I have game film of him doing it)but has an outside range of 38 off the ground!!! Go Figure!

It's probably because of the quality of the fields in high school. The school I was associated with had a natural grass surface with poor drainage that was also used for soccer and resembled a battlefield by mid-season. Even really good soccer players couldn't get a place kick airborne when the ball settled an inch into the mud. Now that a lot of our big schools are going to synthetic turf, I see Mississippi discarding the tee soon.

Yea our field is used by 2 seperate 5A High schools and never gets a break!!! Ther is a game there every week and if we both have home games which happened twice last year one is played on Thursday the Friday game is in trouble. Gets comical (in a sad way).
By mid season you need a magnyfying glass to find grass on the field.
