Shivas,
If you want to see them go lights out, have them play some sort of birdie elimination format (once you make a par or worse you get eliminated, the guy who goes the furthest wins)
What you are advocating sounds like having a tournament where you get a flat fee for making the cut, then pretty much have to win to get any significantly greater reward. Kind of takes the point out of trying for the guys who are in the "including ties or within 10 strokes of the leader" category for making the cut, you'd see a lot of them mailing in the last two rounds once it became clear they couldn't contend for the win.
I don't think risk taking is missing from today's tour, when you see CH III taking that line over the trees on Deere's 18th (still amazed he'd play that shot not because of the carry but because stopping it before the water was just dumb luck) They are shooting at all sorts of tucked pins, granted it is with wedges and short irons, but how much more boldly do you want them to play? I think they play TOO boldly today, that's why it is so boring to watch. Where is the strategy when you FLOG it off the tee and then aim directly at every pin? Its just that they protect their lead down the stretch when they have a big check that goes a long way towards getting into the top 125 (or the down payment for the vacation home in Hawaii) They start to get conservative at exactly the time when they should get the most aggressive, that's IMHO one of the reasons why Tiger beats most players down the stretch when he's in the hunt. The win is important to him, the check is the important to most everyone else.
I just want to see some real pressure enter into it again. Other than trying for that first win or first major I don't think they are under anything like the pressure the guys in the pre-exempt days were. They only feel what those guys felt back then when they are in Q school and when they are 150th on the money list with 3 events left to play.
