JSlonis,
Approximately 280 to 320.
MDugger,
Not really, shots pulled a little left, or with a draw can get blocked by the fairway trees, and drives pushed a little right can now be blocked by trees, and/or caught in the rough.
I'm not sure that shots from the rough to the green will hold the green, unless they're short irons.
John Stiles,
Based on what I saw at the TPC, drives of 300 were fairly common, and that was without the benefit of helping terrain.
Guys were hitting 5-6 iron second shots into # 16, which I believe is fairly flat and played to 507 yards.
If the weather stays dry, it will be interesting to see what the PGA Tour Pros hit into that green, and if I remember correctly, there isn't much, if any room to lengthen the hole.
Rick Shefchik,
That's a really wide fairway, and it would play even more so without that stand of trees, and that might even be the prefered angle to come in from, and it might be the shorter side given the slope and assistance tee balls would receive, so if the trees came out, perhaps bunkers down the left side should go in.
If the weather is dry, and temperatures in the 70's or better, I think the hole will be a drive and medium to short iron for the entire field, unless the fairway conditions are altered by the hand of man.
This would completely undue that which was architecturally intended with respect to the play of the hole.
It would eliminate any decision/indecision and reduce the drama and pressure that was an integral component of the design.
