Me too. Early is always better. Get 'er done.
Plus the early starts are a matter of logistics. The Memorial is played on two courses, and there's a huge field. Gotta spread out those tee times to get everyone in.
This is true. Someone has to tee off early each day. But let's be clear...the women doing it every round at these events is a sacrifice for the sake of video coverage. I would guess that it's one they happily make because the consequence of later tee times is very likely no cameras (or at least, no live cameras).
Whether it's live cameras like with the DGPT or post-produced cameras as seen at Vegas, the larger the time separation between the FPO lead card and the MPO lead card, the easier it is to cover both of them.
