Warringah coach Mike Ruthven is looking forward to seeing how Ben Marr adapts to life as a flyhalf when his side takes on the Western Sydney Two Blues on Saturday.

Marr has been among the best fullbacks in the Shute Shield over the first nine rounds and has been thrown the No.10 jersey in an effort to try and unlock the Rats backline.

The Rats backs have been clunky at times this year and there is a feeling that the attention that Marr will get from opposition defences will see opportunities abound elsewhere.
