Time to try Humble in the mix at 6 I reckon, see what the kid's got this year?
Have either Robson or Maguire at 7 with him, have the other at 14 and then they can give each other breaks if Keating can keep going 80mins (or be there if Keating needs a small break). It's all we've really got for this year, unless SK wants to see the return of Morts... #-o
SK doesn't seem to be good at using the bench spontaneously, or in different ways to match changing game conditions. It's like he has a premeditated structure for it (including the 10 minute use of one player shambles) and always wants to stick to that (even when we had an early backline injury reducing our bench/forwards rotation by one).
As for helping Hayne, the trade off for paying (or signing) players something around the $400K+ mark is that we will have less quality squad depth to help them out. We're apparently under the cap significantly and have let some guys go this year, but haven't got anyone coming mid-season... so next year better have some signings to show for it all (especially if Burt and/or Hindmarsh retire early)!
