Still working this abet very part time...
Looked at some MaxPreps stats...I know, I know, garbage in garbage out. At least in California there are lots of teams from 0.92-0.95. I think the mid point was around 0.92 for the 450ish teams I looked at.
My son's team is young and kicking the ball around a lot and they are 0.89. (these are good stats) So I guess a reasonable assumption would be around 0.92 for a decent team
12's sent me a link and they were at .88 (I suspect they kick the ball around some also)
More to come.
