Yes, more runners ON THE GROUND, but you're missing the fact that the limit means you can't actually use all 4 bench players in a constant rotation. So instead the opposite will occur in that it'll be more like the old days where a ruckman could rest on the bench. Lobbe would play 60% ruck, Ryder 60% forward, 40% ruck, Lobbe 40% on bench.
Using that only makes us a lesser team. Ryder is comfortably a better ruckman than Lobbe, and he's a better ruck than forward too. Ryder is elite in terms of ruck play. Lobbe has never been close to that.
We should be trying to get the best out of each player, not restricting the output of one to keep another happy.
The Club needs to make calls that are best for the Club, not the individual - no matter how harsh that seems.
