I agree that communication is the key. Obviously the field was designed to push everyone forward. The HB NPPL was like that. Sometimes what I do is blindshoot back at where a paint stream originates from. Even if I don't have a chance of hitting them, I get them to stop shooting, which means that they're being ineffective and that I'm controlling them. Sometimes my backman's best position is right on the 40, just behind me
That was how it was for one game this last weekend. We had a talk with my backman about how he was still at his primary bunker at the end of the last game, when his frontman was crossing the 50 and his frontman needed good coverage...so I hit the 50 as my third move and I look behind me and see my backman at my last bunker yelling "I'm right behind you Ray"... we ate them up that game. Because he moved up (some of the center bunkers were large and blocked the back guy's view) he could tell when I was in trouble, and from where and put them down enough for me to do what I needed to.

PS Looking for Refs is a good idea, but be aware that some of them will stand next to an empty bunker just to mess with people.
