On the one hand, I agree that there's a big negative in not having a simple path for a dominant amateur (ie, Johnson, Holmes) to get to play against the best in the world right away when he's good enough to compete right away. On the other hand, the numbers show that the rare exceptions aside, the Nationwide tour as a sort of minor leagues of golf does in fact produce players who are more capable of competing on the PGA tour than the average player who's coming from college or mini-tours and gets hot for 6 days at Q-school. Unfortunately, unlike the team sports with minor leagues, golf is an individual sport so there's no manager or GM who can just make the decision that someone is dominant enough that they can compete at the top level right away.
I do like the idea of a 3 tournament series where the top guys from Nationwide and the bottom guys from PGA compete for spots. How about the best of both worlds? Have a separate pre-3-tournament-series Q-school, with the same qualifying standards as the current Q-school, so it would be open to the best juniors, college and mini-tour players as well as numbers 76 and below on the Nationwide tour, where the top 25 get guaranteed Nationwide cards but are also invited to the 3 tournament series where they can upgrade to a PGA card if they finish in the top 50?
Keep alive the Q-school to PGA dream, but require a sustained 4 tournament proving, but with 3 of those tournaments against Nationwide and some PGA players as well. That would make me even more interested in watching the 3 tournament series in years when there's a couple feel good stories of mini-tour grinders or top college or junior players trying to run a 4 tournament gauntlet and make it straight to the PGA tour.
