I think you guys in Texas have been dealing with lots of mid week games for a while. In my area California, traditionally, Freshman football was Thursday, JV/Varsity (2 games) Friday night, youth and the few schools that don't have lighted field on Saturday. This worked pretty good since most of the Freshman games on Thursday started after 5:30 and most of us that work during the day could make it to the field on time.
Recently, several leagues started play Varsity only of Friday nights and moving junior varsity to Thursday so that we have two games Thursday with the first starting at 4 PM. This has made it much tougher to cover these games, especially in the outlying areas. The schools did this without ever talking to the officials about it. The reason for the change is they believe they will make more money on the gate this way. This doesn't matter to us because we are paid a flat rate.
It would be sacrilege to have a JV game before the varsity game in Texas. And, I sure don't want to work a JV game at 4:30 or 5 the last weekend of August or first few weeks of September when field temps are around 120 degrees, then work a varsity game. JV games will always be on another day.
One other issue we have in Texas is the shear number of players playing football. It is not uncommon for a middle schools to have 3 teams per grade, 7th and 8th, and sometimes even freshmen. There are even sophomore teams at some schools. I've seen a high school field as many as 6 or 7 teams early in the season, and then they want to run games simultaneously.
Requiring guys to work is good, to a degree, but we cannot all work every Thursday, and most of us cannot work more than one SV day and varsity day in the same week. We also have some varsity games on Thursday, taking those guys out of the mix. In fact, we have a policy that does not allow any official to call a SV game the same day as a varsity game, even if they work Saturday morning then Saturday night varsity.
It is simple supply and demand. There is too much demand and not enough young, willing and able supply. Personally, I've been working two sv days a week for the most part and one varsity each week with a few double varsity games a week thrown in there. I'm barely hanging in there working that much and I'm ready to cut down to one sv day a week. The knees just can't take much more. The question then becomes, do guys that cannot work three days a week hang it up or just hang in there and work what they can?
