Doubtfully a popular opinion, but I'll throw it out there anyway. In finance it's common to assume the winners (aka. those that float to the top of hedge funds, investment banks, etc) are worth observing as a result of their apparent success, however it's considered prudent to ignore the winners and instead observe what the losers have done, as few intelligent people in that sector believe a consistent winner is little more than someone who has had a good run of luck.
Following from that, if pg wasn't a "winner" there is very little to differentiate him from what 1,000,000 others have tried and failed. Circumstance and context are a frighteningly arbitrary decider, and therefore I don't think this question is particularly meaningful.
[edit: this is not to suggest that dumb luck alone is enough to create a success, it's just that intelligence and tact alone are often not enough to create success either]
