Answers based on looking at the map, and my convo the other day...
It looks like the idea on #1 is to go back to the edge of grass there...so the putting green gets shifted more onto what was once the M#10 tee per the Hanse plan.
The combo fairway on M#3/M#5 is more because the carry from the new back tee on M#5/C#4 over the hill containing the forward tee will be prohibitive for some...the combined fairway is a bailout with less carry.
Not sure about the range, but seems plausible that it would be in the same place as before.
I think the plan on the M/C#14 is to have a tee to the right of that new green tee for M#11/C#8 on the Hanse Plan...it would basically fire over the M#10 green to 14 fairway. I think using that huge new green tee on the Plan for #14 would put the new tees for C#11 in the line of fire.
I agree with you Pat on the C#11/Primrose#1 tee ball. That tee shot has always been awkward, and I would have to think it would be accompanied by tree removal. Maybe more distance overall allows for more room to move a ball around the trees? Or maybe it forces a shorter tee ball with a 3w and a long approach? My two trips around the Composite for the 2009 Mass. Amateur on that hole were useless...overcooked R->L drive, chip down the fairway, wedge to the green, two-putt bogey.
For me, the setup of the dropshot par three will be curious...the current tee is like 135 max, and you can't see the green from there! Do you move the tee uphill and left onto Fireman's patio? They don't own the land in the corner between M#11green and that tee more than several yards. I suppose they could make a new tee and a level hole teeing from somewhere on the Primrose hole that goes left from the par three green...but that would be an entirely different angle, level shot, and a long walk from the par five green. If it stays at 125-130, I foresee some nasty pins about 18" from the collar...
