OK, I'll break it down.
The Celtics are Rocky.
Apollo is our friend, thus he is a good luck charm.
The Pistons are Thunderlips, all hype, but not as likable as the Hulkster.
The final opponent, be it the Lakers or the Spurs, is Drago, the unbeatable force that can only be stopped with pure heart.
When the Celtics/Rocky finally win the championship, we will celebrate with our friends, however we see fit, don't judge us.
