We have 5 and 7 man manuals -- mostly due to the idea that the old 6 man with two deep flanks and no back judge is unworkable (or worse than 5). However, I don't see schools paying for 7 consistently in the near future, even in metro areas we don't really have the numbers to go 7 for 20+ games on Friday night, and more importantly, its very difficult to get officials trained to work in crews of 7.
So why don't we modify 6 man by putting in a side judge, leaving the back judge where he is -- perhaps moving him over a little toward the press box -- and putting the umpire where he is in the NFL. (I'm throwing in the U here because we've had several U's end their season early with injuries this year and this is coming sooner or later). I know this has been brought up before, but why have we ignored changing what might work?
