Yeah Fyfe is not slow by any means. He's clearly a step off it after the long lay-off but no reason you can't have those 3 up forward.
Logue as well is maybe stretching it although he's as fast as most of our smalls.
I guess the question is who is better at the CHF role, Logue or Fyfe? I think if you still say Logue then there's room for Fyfe in the middle but probably not while he's not 100% and not while Mundy is also in the centre.
If we add Logue to Tabs, Fyfe and Lobb then he's got to replace Banfield as the defensive forward imo. 4 tall forwards won't work, especially not those 4.
I agree re Fyfes midfield time, he's totally and easily still good enough to go in there but not when Mundy is anywhere near the midfield and probably not Brodie either. Fyfe with Brayshaw and Cerra is fine.
Brodie spends a lot of time off the ground anyway so it shouldn't be hard to balance the rotations between him and Fyfe but I guess where does that leave Mundy? Surely he's a perfect like for like Acres replacement.
