McNamara or Cayless - who has hardest job in Hull?

First in Cayless' in-tray will be finding the key to unlock the best form of influential half-back Mikey Lewis.

On too many occasions last season, it was a case of if you could stop Lewis, you could stop the Robins entirely.

Cayless will need to tap into Lewis, as well as finding more creativity on a consistent basis from the other backs at his disposal if former Man of Steel Lewis is misfiring.

Despite the focus on evolving the current playing staff, the Hull KR board do not want a 'Willie Peters mark two' type of coach, even if the Australian guided the club to their first league championship in 40 years.
