5 subs is stupid. 3 subs were far better. Now, you can replace half the outfield players, which basically means you can change tactics completely. It means more of the result is down to the manager. It also means there’s less need to prioritise which games are important, you can start with your best 11 every game, and just substitute later if the result allows it. It also benefits clubs with bigger budgets more, as they can afford having a higher quality bench.
You’re right. It is an unpopular opinion. The game is better for it. There have been hardly any 0-0 draws. Yeah the games can turn on their head in middle of the game but that’s not a bad thing… it’s just made it more entertaining and competitive while also helping player welfare
