Age old saying, A good big un will beat a good laal un!
All teams try to get big man on small man, half backs around the world all occupy the same defensive positions more or less and unless they get protection the result will be the same.
Forber is not the only issue with our defense out wide, we have had similar problems for the last few years even when he doesn't play,
For me there are two main issues that we need to address.
1) Forward power, unless your pack can compete and tire out their opposite numbers you will get this all day long, All Golds had 2 excellent front rowers who ran hard all day long creating space out wide for their outside backs, we struggled to handle them despite the heroic attempts of Stevie Scholey.
2) Defensive reads, some of the defensive plays by our middle defenders are very poor, constantly coming out of line and missing thereby leaving the smaller guys with too much to do. I made the same point from the last game when Scott Rooke was left with 3 attackers to defend on more than one occasion!
