Heavy forechecks are easy. I know, we didn't do it very last year, but they're a lot easier to run than a purely defensive trap which requires timing, precision, coordination, and patience. And they're a lot easier to run than a purely offensive system a la Washington of a few years ago, which requires high-octane skill and speed (Ovechkin, essentially). A heavy forecheck is all about skating really hard, hitting someone, causing the other team to panic/get confused/etc. It's easy: go hit someone. As long as the other guys follow the system, it's very likely that the puck will come to a predictable place eventually, so we'll have a plan for that.
And it's not like you can 'game plan' much against a heavy forecheck. "OK guys. Go get the puck quickly, try to pass it before you get smashed into the 3rd row. The guy that gets it, watch out - you're about to get steamrolled." - Ok fine, you know what's going to happen. But that doesn't mean it's easy to operate against.
A heavy forecheck is, at least to me, the best system for this team. You don't need high skill. You don't need defensive poise. All you need to do is be able to skate hard, hit, and know the routes based on what the other team does. The forecheck and the turnovers it creates will provide enough offense that, as long as a few guys have some skill, we won't need to depend on one line or one player to carry the load. Our 4th line was magical during the cup run because they scared the crap out of the opposing D and pounced on turnovers. Not because of skill.
