SEC wants high schools to play NCAA rules ?

[SWFLguy]

On a college football board I frequent-
a poster said that the SEC would like the high
schools in the south to play by NCAA rules as
they do in Texas and Massachusetts.
The rationale is that they won't have to re-teach
blocking techniques and blocking below the knee
would then be legal in high school play.
He said that statistics show there is no more or less
knee injuries in TX and MA than in the states that play
by Federation rules.
I find that hard to believe.
Does anyone here have any knowledge or link
to a site where statistics on those injuries would
be available ??
