The D man is dead wrong in this case. No one looks behind them, it's f***ing impossible and useless.
You probably did back up too much, so that's the thing to fix. It's tough, but I'd say halfway between the opponent's blue line and center ice is where you should be transitioning to skating forward, then trying to angle the guy off towards the boards. So from center to your own defensive blue line you'd be going forward.
Kinda unrelated, but make sure you give the D an angle/lane on breakouts as well. I was playing in a league a bit low for me, switched to D sometimes just to keep it interesting, and I was flabbergasted how much my linemates sucked at giving me space and opportunities. "Pass it up, break out!" Mike, you're 3 feet to my left and right in front of their center, I can't pass it to you. Move. Go. I have the puck, give me something to do with it. The offense was so worried about D that even when I had the puck and it was time to transition everyone was still flat footed in our own zone- not ideal.
