Not sure I put it correctly but I would like/suggest that we just have a tactical option that would allow the losing team to spread the minutes, or in other words, put the subs on when the team is losing in "garbage time" (or the game is out of reach late), much like the winning team.
That way we would have the (natural/logical?) tactical option of always going for it in balanced/reachable games but also to recognize the opponent's superiority and not overtax/overstretch the same guys when the game is clearly out of reach.
I suppose this is something that makes sense and is doable?
