This is actually a sort of interesting idea.Based on need butters playing as a back line small would use his attributes of running at different angles and setting up play. He can tackle ok, ok endurance and be able to go with small crafty forwards.
Long-term if we're gonna win a flag Butters absolutely has to have an impact in every part of the ground in about 3 years time. Wouldn't be the worst idea to have play in a role like this for his development, at least some of the time.
