Some of the difference in golf strategy is technology & technique. Nicklaus only carried 2 wedges, and they were his worst clubs, while Mickelson carries 4 and they are his best. So modern drivers can better afford to miss fairways if they can get within 1XX yards of the green.https://twitter.com/CovfefeAnon/status/1118001242817560576 …
Mikelson carrying 4 wedges and them being his best clubs are related By carrying 4 wedges he can minimize the "touch" needed for shots and instead take a better club for the distance The exchange is missing longer irons that aren't accurate enough to get in 1 putt range anyway
