No and no. They are Professionals who play early tee time and late tee time on Thursday and Fridays every tournament. Teeing off early is nothing new to them. The players going off 10 tee are too far back to have any chance of winning.Think anyone will have an advantage/disadvantage with starting at 720am on Sunday instead of the afternoon? Also same question with them doing teeoffs on hole 1 and hole 10 instead of having everyone start at hole 1?
