Hard Knocks just doesn't sound right with the current coaching staff. That's probably the problem.
Plus, Arrested Development was already a TV show. Come to think of it, LOST had already been taken too. Oh crap, CURB YOUR ENTHUSIASM was already used as well. GET SMART too.
They sure as Hadescan't call it THE DEFENDERS.
Then, there's a problem with naming something too close to previous movie titles.
APOCALYPSE NOW,
TROUBLE IN PARADISE,
LOST IN TRANSLATION,
FAILURE TO LAUNCH,
HOPE FLOATS,
SOMETHING'S GOTTA GIVE,
STILL WAITING,
BLOW OUT,
A SERIES OF UNFORTUNATE EVENTS,
THREE THE HARD WAY,
THE LONG GOODBYE,
THE DESCENT,
THE CRYING GAME,
CLUELESS,
ARE WE THERE YET,
AN INCONVENIENT TRUTH,
DAZED AND CONFUSED, and of course, for our Defensive Coordinator exclusively, ******.
Yeah, if you don't have the right name for the topic, it's just better to wait until something not already used - fits.
