Aye, I’ve been one of the biggest “3 subs is fine” folks and I honestly have still not seen a convincing argument that 5 subs is that much more helpful. At the end of the day, rotation is most important for player fitness and “player welfare” seems to go out the window in the in-game situations where subs are made.
I haven’t had anyone really able to convince me that the 5 subs rule is anything but a way to allow top clubs the chance to play their star players more
The data right now shows that top clubs aren’t putting player welfare first - that’s only a concern once games are up by 2-3 goals.
We had to make 3 injury subs last weekend, and I still don’t blame the lack of 5 subs for it. One of the injuries was a head injury, one muscle injury was to our LB who was expected to play 90 minutes (as evidenced by the fact that we had no reserve on the bench) and would’ve never been subbed off proactively, and one was a contact injury late, where the gaffer really should have already taken Ingsy off.
