Not the place to discuss it since this is more of a swing speed thread, but I doubt you "average" anywhere near 250..
You could possibly say that when you actually hit it well you might get it near 250, but when you talk about average you need to consider those hits plus your 30 yard worm burners add the 100 yard then 60 yard slice shots.. Don't forget the duff shots off the t you probably hit too..
He could be long and off line. He looks strong, and as Erik noted flips, so off line 260+ is quite possible. Given this, I can easily see scores in the 90s.
My son partnered with a kid on the opposing team who averaged 300 yards off the tee one shot 330 yards and ended up 99, while my son had an 87.
