Yes, injuries are part of the game, so it's a bit hard to discount the Lakers title last year by claiming things would have been different but for KG's knee. That said, the way the playoffs played out last year, I was left with a strong feeling that the champs (in this case, the Lakers) won by default. The Lakers were a good, but flawed team that won the West because...well...someone had to win. Orlando was a flawed team that got a lucky break by facing an injured Celtics team. As luck would have it, they happened to match up well against the Cavs and the rest, as they say, is history.
I know I'm a Celtic homer, but I had no doubt in my mind last year that the Celtics would have beaten the Lakers. And that statement is different than Laker fans saying the same thing about 2008 with Bynum being injured. Boston was king of the hill before KG went out (in contrast, the Lakers had proven nothing before Bynum got hurt) and no team (no, not Orlando) asserted themselves in such a way that proves they deserved to take over the throne. Obviously, as others have noted in this thread, this series will prove (or disprove) these assertions once and for all. I look forward to it.
