100% Cotchins win. The centre bounce would be a Cotch fest. I doubt the rioli's would be still on the park after 4 quarters against 18 Cotch's.
The goals aren't in the centre.
But the durability issue is an interesting one.
How quickly would it be 22 Cotchy's against 12 on the field, 6 getting a concussion test, and 4 down in the rooms getting painkiller jabs.
