Basically you want to keep playing Madden ball.
But joking aside, the bold could be false. There could be a very obvious GAMEPLAY reason for this to be in the game: to limit the amount of time people have to EXPLOIT the game. I'm quite sure that's a big reason why they did it. Especially if they are looking to go the e-sport route.
And if it
isn't a reason, it's a wonderful side effect.
