I think Elliott will end up at 4, Ginobili at 5, and Parker at 6. Gervin is a mortal lock to be 3. The question between 1 and 2 (or 1 and 1(a)) is whether keeping the franchise in San Antonio and single-handedly making the team a championship contender will outstrip 3 rings, 3 Finals MVP trophies, and 2 MVPs (along with everything else). My guess is that it won't; that Duncan will be #1 and Dave will be #2.
