I agree as well... seems much more logical, easy to follow, and provide a potentially more dramatic finish. Only have two issues I can think of...
1) Under the current system, any of the top 5 going into the final week can win the Fedex Cup with a victory. But - under the new proposal - if someone were to tear through the first playoff events and create a massive stroke lead, you could have a situation where they play conservative at East Lake and remove any drama by the final day. Not saying that player wouldn't deserve it, but it could provide a boring finish
2) What if a player were to win one of the first playoff events, but miss a cut in the next one? He would then be DQ'd from the next event, despite still being in the hunt with his cumulative score. Should he receive no protection from the cut in smaller, more competitive fields?
