Pretty harsh assessment IMO broSo you don't even try, you give up. But you're wrong. Look at the tape again. Those three players didn't know what Croker was going to do, so they watched instead of making an angle run to the try line in the corner to cut him off. So you are encouraging trotting instead of running. This isn't horse races.
Shaun Johnson is obviously way less than 100% (Crocker ran him down with ease when Shaun Johnson made that break in the first half), Fusitua had actually come from the left side of the posts & did well IMO to even be in that position (as did a flying Lolohea who actually got the closest, but Crocker still gassed him as well) & Afoa was always done for pace & by the numbers the Raiders had out there
The far FAR greater concern for me was Leilua & Rapana making Kata, Maumalo & Hoffman look decidedly less than average when they made that initial break down our left edge which led directly to the try, our line (especially our right edge) never recovered in time after that which essentially gave Canberra a 3 on 1 overlap which they were always going to score from if they got the ball out there, which they obviously did
If the Warriors had actually managed to stop Canberra from scoring in that position then it would have been the defensive play of the last two seasons from us IMO
