Hello, you can see by my username which team I'm a fan of, but I'm not here to gloat. I posted here when my team was crap.
Ultimately, it came down Lebron and AD basically guaranteeing about 60 points per night, plus Rondo performing. From there, it just came down to whether the role players could give you anything. Typically, throughout the season and playoffs, whenever the role players made three's (or just otherwise performed), it was a likely win.
Also, avoiding a prime Clippers team / Bucks team and playing the Heat (with injuries) helped. I'm honest enough to admit it. With that said, teams do benefit from injuries all the time - Look at Toronto, or look at GS when they played Lebron's Cavs with all their injured players.
