I believe you're over-thinking it, or at least the point I was trying to make.
I was speaking solely to the starting streak and the likelihood of him beating out Pau, Dirk and Durant at this stage. I'm not arguing the ability, talent or who I would rather have in a postseaon game.
Look at it this way, Pau's a virtual lock (rightfully) to start. Even if it was close, he's a Laker and is going to have the numbers.
Now, that leaves one spot, and remember how Tim barely beat out Dirk at the last minute last year on the vote. Also, think about the injuries the Spurs have had the last two years that forced Tim to play harder and at a higher level early in the season. Those cir stances dictated Tim putting up some pretty impressive numbers and put forth the notion to the vast majority of fans that he was still Tim Duncan.
So if you look at it now, Tim's finally being afforded the opportunity to take a bit of a backseat and coast to some degree. After 2 years of having their long-term plan for Duncan's regular season slow-build go up in smoke, they'll finally be able to not deviate from the gameplan (knock on wood). And with that thinking it's hard for me to see Tim putting up the numbers and putting forth the perception to the masses (the average NBA fan) that he should warrant a start over Dirk or Durant -- Dirk will be leading a team amongst the league-leaders in wins, putting up more impressive numbers, and Durant may be the most popular player on the ballot; also putting up some pretty gaudy numbers of his own.
But Tim does deserve to start, and for the position he now plays: center.
Maybe it should have happened a year sooner, and maybe it was a blessing then that he didn't given the Yao factor, but there's no doubt it should happen now -- both because he's deserving and it allows the West to field their best starting 5, all of whom would be playing at their natural positions (at this point in time).
