I'm not saying it right or wrong mate, but with the options avaliable and given how well o toole has been playing I would have played Mcwilliams (1st option), (Foley 2nd option) in that holding position before sacraficing jj from just behind long. That is just my opinion.
I know it's a game of opinions, but I'd be interested to see why you'd play Foley in the middle ahead of O'Toole? O'Toole was in League 2 team of the year in this position, and probably our star player in the same position last season.
Foley has looked far too lightweight for me in the middle. Seems to lose most 50/50s, poor positional play and doesn't offer much in ability. I personally think his work rate and stamina is definitely better appreciated offering balance on the wing.
