For swing......I agree, Freddy Couples hands down. Very very few have that good a tempo and smoothness, coupled (yes pun intended ;) ) with power. Have seen him play several times and nothing seems to bother him.
Second would be Phil, I was lucky enough to play with him a couple of times when he was going to ASU and I was living in Scottsdale. Now THAT is a magician with a wedge. He can do more with any short shot than anyone I have ever seen (on TV or in real life)
As for Jim Furyk how can you say he has the worst swing? Maybe an unorthodox take away, but, to impact he has probably one of the BEST approach angles of attack out there.
But that is just my thoughts
God Bless and have a great day
