The only time Will has played his best footy is when he's thrown in the deep end as the sole ruck. Give young blokes responsibility, back in the development and coaching of these two.Don't take two ruckmen that have played 20 games each and go "Ok, we've got rid of Minson. We're challenging for the 8 this year. You guys are carrying the ruck division, good luck "
Keep Minson, but rest him a few times, have Cordy/Campbell be the ruckmen in a few games with no Minson or anyone else to help out. If they're ready, then Minson can go end of next year. But don't just throw them in the deep end.
