Kentucky,
I am from Northeast Ohio area and I think for the most part, most of Ohio work crews on Friday night. Here in Northern Ohio there are a number of 4 man crews that work together on Saturday morning. Each crew has a crew chief (me) on my crew, and we get all of our games through assigners. I have only worked varsity games on crews, so I know no other way. But I can tell you, after working several playoff games where we are assigned by the state of Ohio, You certainly loose the connection of your crews, working with 4 new officials. I know on any type of play, when I look up, who I am going to see, when i have to turn my back to the field, I know either my R or my BJ will be covering my back side. Plus when you work in a great crew with great guys, it is a pure pleasurer going to the games. I have worked with crews where the chemistry has not been good, and that makes for along night. I have read on this site where posts like this were asked, where some assoc. have a draft every year, breaking up crews. I would be willing to talk in my assoc. for a plan like that. The only plus I can see for assigning each position for each game, it would give newer officials to get a chance to work varsity games sooner. That is a big drawback for assigning by crews. Newer officials can not break into older crews, and thus do not get a chance to work varsity. I also can see the assigners point of view, where instead of him making 5 calls to fill a game on on a Friday night, He makes one call early in the season or as our do, by e-mail and the Arbiter and he can take care of whole season. I didn't really come up with anything different than the other posts, just explained how we do it in Ohio
