Cowboys finally have the depth to

North Queensland captain Travis Norton believes Brisbane's one-time poor cousins finally have the depth to be considered an NRL power club after thrashing the Broncos on their home turf.

The Cowboys hammered Brisbane 36-4 at Suncorp Stadium yesterday, with their reserve grade side, the Young Guns, also inflicting a 36-10 belting of Broncos' feeder club Toowoomba Clydedales. It was the Cowboys first win over the Bronocs in Brisbane since joining the NRL in 1995.
