I agree with you that the flipping of the starting times will even out the field from a bumpy yesterday, smooth today perspective.
Remember, we have not had a lot of warm sunny weather here in the NYC Met Area, so the Poa has not firmly bloomed and blossomed yet. I am not an agronomist, but what I have noticed from playing in this area for the last 40 years is that once the heat comes and stays, the Poa blooms and then wilts. Once shaved, the greens will be fine if the heat and humidity cooporate.
Could this be a ploy from Tiger to get the USGA to really bring the greens speeds up (And the scores as well)? Personally, I don't think so, but making the course even more difficult would be a benefit for the world's #1 player...
