Injuries, mostly, including mid-season injuries.
Injuries dictated moving Perk. Injuries cost us on the court.
Give me a healthy Marquis, Perk, Shaq, JO, Rondo, BBD, and Delonte, and I think we beat Miami in 6, at most (and that's assuming they had a healthy Haslem). Unfortunately, injuries are part of the game, and we gambled on injury-prone players. It just didn't work out.
