Honestly, the C's didn't scare me that much when they formed from a video game perspective. KG, Allen, and Pierce weren't athletic players during their time together. Rondo couldn't shoot for nothing. Perkins was Perkins. After that, the bench was manageable.
The Celtics were like the yearly Spurs. The general gaming community will mostly ignore them, but they're a damn good team when you know how to use them. As for the Heat, Lebron was a household name and was greatest player in the game. Wade was torching my *** for years before that. Bosh was a quiet superstar who went largely ignored by gaming community, because he played for Toronto. Just by name recognition alone, bandwagon players were going to use Miami by far. Same thing will happen with GSW this year.
