Why all of the sudden is this a big concern. My 14U son wrestled on a 1/4 mat last weekend as did all 14U up to 125lbs and nobody said a word about it. So why you all bitching about this week. The mat in question was a 36ft X 36ft mat, 3ft boundries on both sides and that makes it 30ft, cut it in half and that makes it 15 X 15.
