Actually, reducing the play clock to 20 seconds would mean more plays, and therefore likely more injuries/concussions.
You'd shorten the game. You could have shorter quarters.
Huddling gives players time to catch their breath between plays. If you can't catch your breath, you are going to need to focus more on endurance and less on explosion. Smaller, faster, more in shape athletes will dominate the game.
