I'd be keen on Butters, but I always come back to a different idea: instead of paying him $2m/year, would we be better off with 2-3 players at 650k-1m/year? Surely taking Butters wouldn't put us at 100% of the cap, so we could look at guys like these.
Zac Bailey - reportedly being offered 1.2-1.5
Ben King - reportedly being offered 1.3+
Bailey Williams/Kieren Briggs
Surely you'd think a Briggs/Bailey combo would end up costing similar to Butters alone. Bailey has been playing more midfield lately and is a gun IMO.
