I'm on board with the middle ideas, especially the Porter one, as he was highly regarded as unfit before he appeared with us, by the Oldham fans.
We, as a club, in my opinion, in recent years, have been phenomenally good at managing training and the general health of the squad in order to manage illnesses/minor niggles. If you look at our first team, we're very very rarely without members of it, outwith lengthy absences (say 4 weeks or more), so it's perhaps an offshoot of that, for players like Porter.
Again, what I've heard may be utter bullshit, but it's something to keep in the back of the mind perhaps. No more than that.
