Fox subsists on a steady diet of mid rangers and he's also 7 years older, so of course he's more polished.
The last part is hypothetical and likely years down the line, exactly the sort of thing a team in the infancy of a re-build has no business so much as considering.
Too many are consumed with prescribing problems and reverse engineering something that hasn't even occurred yet. Paralysis by analysis.
A lot of them have this idea that because this franchise has had Robinson, Duncan and briefly S bag playing at a superstar level basically in succession, that they'll just luck into another one in relatively short order, so why settle for anything less or that whoever takes the torch has to fit the ethos of Robinson, Duncan, Ginobili and to a lesser extent Parker.
They don't get that the odds of either are astronomically slim and that this draft is essentially the beginning, not the end.
