There's an alternate universe p.o.v. that had Garnett and Powe stayed healthy, the Lakers would have been automatically beaten in the '09 rematch finals.
I'm not really convinced of that. In '09, both Ariza and Odom played their hearts out, unlike in '08. In addition, Bynum was healthy and contributing. That '09 Lakers was an upgrade from the prior year's *Kobe Ball* squad.
Next, the Celtics bench on '09 was inferior to the championship year
Here's the '09 bench … Moore, Marbury, House, T Allen, & BBD
versus '08
*Big Game* James Posey (basically, 6th man of the year), PJ Brown, Cassell, House, T Allen, & BBD
So the added advantage of us, tossing the kitchen sink at the Lakers, was reduced in the 2009 rematch, esp when Odom and Ariza were fighting for new contracts. We all know that Doc's rotations aren't the best in the league.
In my alternate universe, we lose in '09 but we clearly win in '10, as we had an Operation Fo'Fo'Fo' thing going on that year where pretty much, none of the opponents had a chance against us, starting in the first round. The Lakers winning that year was an abomination in officiating. The 2010 playoff run was the best in the post-Bird era, as we were undefeatable.
