Agree. Though right now, FSR has the edge over Filler in performance in majors cos of better break, better game management, decision making, mental game though he may slump in next 12 months.
Of cos in terms of pure natural talent , technical ability Filler has edge over FSR but winning majors is more than just talent, technical ability- there are non-technical aspects game management, mental game.
FSR sudden rise in the past 1.5 year has been phenomenal for relatively old player in early 30s, someone who was a junior World Champion lurking high in Fargorate rankings for decade or so but never won anything major then suddenly out of nowhere won a slew of majors.
