Relax guys. With Big Dave still not ready apparently, no need to change the current BL structure. In principle, don't mind the idea of Floss being tried in the middle again in lieu of currently missing our tough inside mids.
Balta could be freed up to play ruck relief in there too when Dave returns, resting forward. But only if we meet opposition where we could do without Soldo to combat a highly mobile opposition ruckman i.e. play Chol as No.1 ruck. I'm thinking about the Bulldogs' English for example, who covers a lot of ground, takes vital marks but not so good at CBs as yet.
I concede very unlikely but would be a daring combo: highly athletic, skilled, fast and aerially threatening, dangerous near goal, super mobile talls.
Not so related but IMHO, it's our forward line that needs to fire up and get their act together if we are to beat the likes of GWS. The BL has saved our arse thus far.
