I find this thread interesting. JB took 4 minutes and 10 seconds to make a shot on the 18th hole where he clearly had a decision to make with a possibility of a "win" and the media jumps on his case and the herd follows.
I like Jordan Spieth, but Jordan took 20 minutes to play his shot in the Open and it was on the 13th hole - not on the 18th.
Personally, I would have taken as long as it took me to be settled in my own mind about what to do. Even when JB did take the shot the results indicate he still was not comfortable with his decision.
