The team has quit..

They've pretty much just given up. We are down to 20 bodies, and other then 4 kids, they just don't care anymore. We are 1-5 (and in my wildest imagination about this season, I thought we would be 3-3 at this point, maybe 4-2). We couldn't run an offensive play to save our life during practice yesterday. We had 21 plays, ran 1 correctly. ONE. We stopped offense and moved over to D. 
As the OC I couldn't see straight I was so frustrated. 
They just don't seem to care if they get beat or not. They don't seem to care if things are going well or not. I've been a jerk, I've been a nice guy, they don't respond to anything. One rumor I heard from a player is they don't like the HC, who is a screamer, and don't wanna play for him anymore. 
This week we have a game by all accounts if we show up, we should win, however, I thought that twice, and we got rolled. 
I can't make the offense any more simple, I've teached it every way known to man to adjust to their learning style, yet nothing. Im just tired of spending what little free time I have watching film and game planning for them not to care. Any ideas what to do at this point? 3 games to go.
