I read comments like the one from JakaB above and wonder if someone like him every has played a competitive sport and understands how pressure impacts performance.
So, for JakB's sake, let me explain why scores are usually lower in the first round than in the 4th round-THEY ARE UNDER MUCH BIGGER PRESSURE IN THE LAST ROUND!!!!!
So, you can complain about course setup, conditions, watering, etc, etc, etc, etc....But, at the end of the day, these guys ARE good, and if you put them in the worst of conditions for a $25 Nassau they will still be way under par-put them out there for a Major when they are in contention, however, and it can be a totally different outcome.
