DAZZA501:
The player who shot 76 doesn't have a 64 degree wedge equipped. This is where the shot difference is coming from.
if your irons are dialed in, you don't necessarily pull out the lob wedge all that often unless you miss the green or par 5's but course management can help with that.
that said, I still agree with you that not carrying a lob wedge over the long term would very likely show up in a players recovery stats...bunker and par saves when missing the green. now an elite or top player very familiar with their wedges could possibly manage quite well without a lob wedge but doing so requires you to hit more finesse shots around the green in the 5-15 yard range that a lob wedge would easily handle --why force yourself to do that though?
as you probably know, some of the SOTW tournaments don't even offer any specialized wedges ( gap, sand, or lob) and players still find a way to shoot very good scores. the key of course is the approach shot and learning to hit to a lay up yardage if you can't hit or hold the green so that you have a full pitching wedge in rather than a very awkward distance. at least that is how I have tried to manage when I have attempted them..
