Yeah I could ask them, but I reckon Dobson, Fox, Murrell, Watts, Welham, Fisher, Lovegrove etc would be much more insightful.
Hey in any case:
Ratu - injuries have slowed his progress at Rovers, not coaching IMO
Cooke - personal decisions cost him his career I reckon
Wheeldon - done a solid job at Rovers so far, same as he did for Hull
Mills - pudding, no coach can change that
Briscoe - disappointing season in 2010 by his own admission, but overall a fantastic player for Rovers over his three seasons, so don't get his inclusion there.
