Yes, Popovich has managed a great 1st game against Miami.
In all honesty, Parker is an excellent PG, however, he's not as naturally gifted as Rondo. Rondo, throughout the big three era, had relied on his natural gifts [eagle-eye pass { for fat assists total }, mini-dream shake layups, etc], instead of developing into a JoJo White style super combo guard.
In essence, Pops had done that with Parker and today, he's the most consistent PG in the west, able to finally compensate for the aging Ginobili, the mid-2000s Paul Pierce of the west. Thus, the Spurs have JoJo in his prime, an older PP, a mature Admiral (ala Duncan's role) and a complimentary crew.
I believe that had we had Pops, the 2008 run would have been 4-1 against Detroit and 4-1 against the Lakers. Kobe, at most, wins that game 3. The historic comeback of game 4 wouldn't have happened, as we'd simply win it. And finally, that hustle/bustle of game 5 wouldn't have neted the Lakers a win. The 2008 Celts were stacked, with talent across the board. Pops would have maximized the talents of that squad. Instead, Doc simply hoped for Thibodeau's schemes worked and prayed for the rest to fall in line. Sure, with Ariza & Odom not playing for a future contract, that wasn't a big deal.
