Toovey is being short sighted - It's not the amount of penalties in a row that's the issue - I believe that was done to hide the fact that the Tigers had incorrect decisions go against them, It's where and what they were for.
His team were repeatedly picked off for slowing down the ruck, and not being square at marker when our lads were gaining momentum, and defending on their line - that's really no biggie in the modern game.
It's when players get taken out during a jostle for a try, or when an obstruction leads to a try - That's where it's crucial as points are on the line.
