5 shot lead making the turn? the field needed help, he gave it to them with a monumental collapse. Jordan was fighting his swing Sat and Sun, specifically off the tee. Couldn't find a swing he could trust.
a good caddie can have a significant effect on the outcome of his player. After his first shot into the water at #12, Jordan must step back, re-group. Caddie MUST play psychologist here. That second shot into the water wasn't even close. Clearly, he wasn't mentally prepared to take that shot.
for me, Jordan lost this tournament. Kudos to Willett tho, hell of a finish 16,17,18
