Could it be a good idea or bad? I personally think it might be interesting like that. Have 3 substitutions and a bench full of players. This will give more players a chance and reduce exhaustion from going OT. Normally after OT game becomes a battle of mental and sometimes it feels sluggish. If substitution existed then the game could possibly maintain that early game energy? It will also reduce whiffs and the game will be more skill-based. Just my personal opinion. Thoughts?
