I agree with a lot of what you said in this post. However, your last line, while maybe accurate, I am not sure that Moore and his staff feel the same.
We were subbing kids in pretty much every play, and not just receivers.
Shoot, the young Lennix was carrying the ball on our second series. While I firmly expect him to be big factor the longer the season goes, I doubt that he will be carrying the ball that early in the Moeller game.
Our team is so young this year, it appeared to me that our staff was trying to get as many kids on film as possible against Avon's first unit to see who can compete against that caliber of opponent and who isn't quite ready, to attempt to establish some type of depth chart.
If anyone stuck around for the JV portion of the scrimmage, other than a handful of kids, a lot of the kids that started in that portion of the scrimmage were kids that played liberally in the varsity portion.
Also, keep in mind, Hartson only touched the ball 5 or 6 times the entire day. That will most definitely change in 2 weeks.
