I don't think that is exactly what he is describing.
He's suggesting we didn't rotate Akpom - so when he was injured we lost our attacking threat for 1 game.
The solution to that would be to have a good backup player for the very few games in which they're needed, which is what I'm describing.
If we rotated Akpom last season - we'd have lost a large % of our goals - and probably wouldn't have made the play-offs to lose him for that one game.
You can't have the best of both worlds.
