that the best score tomorrow will be +2 isn't very farfetched. i think it will be at par or worse. the problem with your scenario is that if the best score is +2 and the leader will be at +1, that means only nick dougherty or angel cabrera have a shot at it by shooting either +3 or +2 (best score of the day) respectively. i don't quite agree with that one.
yeah my scenario is kind of messed up haha.. we'll Doughtery could shoot +3.. you never know
Cabrera is also capable of shooting +2.. I think I'll stick to my crazy scenario!
of course, it's possible. they both shot the 2 best scores of today but i don't think they're going to repeat that tomorrow by shooting the 2 best scores again.
