i disagree. there has to be a time to rush up and a time to slide. mid field and when you've got them under the pump down their own end, bringing the whole line up makes sense, it physically stops the attackers from making meters. we rushed up against the Broncos for the first 25mins and completely rattled them. they had nothing, nowhere to go, we destroyed them right then and there with that tactic.
sliding seems to be more useful back on your own line when defending a potential try. we have a pretty good structure here and are generally pretty successful. but when you try and slide around in the middle of the field you bleed meters. want proof? the last two games. it's an easy 10m before they attempt a tackle and many times the forwards are able to milk a few extra meters. Dragons went about 60+m several sets on sunday when really we should've got up on them and kept them deep in their own territory.
Rushing defence takes a physical toll even on elite athletes that it can really only be sustained for a short period. No team can rush off the line for the full 80. There is a reason why we dropped off after 25 in the Bronco's game. And sliding on your own line? WTF?
