I really wonder sometimes if I'm watching the same games as other people. In the last two games, Ford was 19-1 for tackles, the 1 missed tackle was a great hand off by Davies, which has done far more than Ford. Ford had Parkes coming down his channel repeatedly and didn't miss him once. Farrell on the other hand misses a ton of tackles, as he get's bounced off or just stepped. Farrell needs to be covered in defence as he regularly leaves dog legs and misses when he shoots up. I know the press like to vomit all over his big defence, but it's a myth. And the whole "misses don't really count, since he's forcing them in just like sarries" is bollocks too, no other 12 (or 10) in world rugby misses as many and causes so much panic in his own defence.
Francis repeatedly broke the line, beating 6 defenders and making 2 clean breaks. At least once that defender was Davies, again, no mean feat considering JD2 is considered by many, to be the best 13 in the game at the moment (I'd agree).
You cannot rely purely on running straight into a defence with power, I agree, but when you have multiple power options, and a half decent 9/10, and/or decent hands in the forwards, then suddenly the defence cannot cover everything. You cannot expect to stop Mako Vunipola on the gainline with a single defender, but if you commit 2, then you worry about him getting the pop off to Sinkler, or Billy, and suddenly they make 5-10 yards. Manu has the same effect, it takes 2 to safely defend him, so have him at 12 with Ford at 10, and suddenly if Manu makes a run the defence tightens, if Ford then chucks it out to Slade or Joseph, they're in trouble. Especially with pace like May/Watson/Daly/Coka out there.
The most physical team nearly always wins. Now that's not to say it's all about size, since a fair bit about it is also attitude, but watch the all black pack to see physicality. The ABs play some very very pretty rugby, but their intensity and physicality in the pack are generally unmatched, when they are matched, that's when we see them stumble. The secret to their winning streak isn't the likes of Mo'unga or Barrett, it's the likes of Retallick and Cane, absolutely blitzing rucks and tackles, every time, every game. They win with the psychology that allows them to reproduce that sort of effort virtually every game.
Ireland had the same intensity when they were dominating for a while, though they dropped off a bit.
England rarely match that intensity, but can replicate the physicality simply by having the likes of the Vunipolas and Sinkler etc, these guys are big enough and skilled enough to be able to do well, even without that insane intensity. But when we did last produce it, we were one unfortunately pulled back try from beating the ABs, and that was with a far from first choice pack, but playing with a really high intensity.
