I agree it would make the defense more impenetrable, but yet the defense would also never get a turnover if they didn't contest the ruck and a turnovers happen all the time, that is why a love the rucking aspect of rugby as brutal as it , it really is like a chess match.  Plus the defense has already got an xtra weapon, with the quick pick up if they isolate the player.   Is quick pick up at ruck available for both side of the ball, because I only saw it used on defense in one of the videos?   Later I will detail a ruck system, that I have been thinking about for 4 years now, it is based on the system we have used in the past with a few modifications, don't know much about programming but I believe it would not be a difficult system to implement because it is similar to what you have in place.  In any case I am happy that you guys are trying different avenues with the rucking, that is how things get improved.   "On a funny note my xbox 360 just got the red ring of death last nite, can you believe that, just before the demo.:lolI,m hoping its released in US xbox live)(Got a ps3 but don't know when demo will be released in US).   Good news I hald my ---- over this morning to repair shop(put every thing else on hold), they should be able to fix by 4:00pm today. And that is why I was able to laugh about it !!!
