McShane has turned down a contract at Cas. Might be putting two and two to make five, but Clarke to Australia and McShane to Wire with the new coach doesn't sound too ridiculous.
Be interesting to see how long Liam Watts and Lee Radford stick together now Radford has the Cas job. They fell out at Hull (and Radford isn't somebody to fall out with). Watts moving from Hull to Cas was a lever in Shaun Wane wrapping up at Wigan. He wanted him at Wigan, and he might be the prop that they have been looking for for 2 or 3 seasons - physically imposing, a damaging carrier, long minutes, 100m + per game. Having said that, he looked a yard off the pace against Wigan last week.
