I think the PGA Tour would be so much better if we had opponents utilizing a brush via the "curling" aspects on the putting greens on tour. It would make the game so much more interesting.
I can hear Ian Baker Finch calling it now.
"Oh, he struck it well... the ball is rolling along nicely right into the cup!"
"Wow! Credit Jim Furyk for brushing the grain away from the hole at the last second, and who knows how his opponents might respond on the looming 2 footer he has!"
Can't hurt the tv ratings.
