FWIW, WF did get the Elite 8 in 2019, the last time that there was a season, and WF did get the Sweet 16 this year. I have no idea the role of a golf coach on the college level other than to bring in highly rated recruits, which Haas does. Golf is such an individual sport, and all or most of the players have their own coaches/pro's/parents that help them with their games. It's not like the typical team sport where there is a particular gameplan versus an opponent. Did Haas do a great job coaching the team in round 3 when Parker Gillam shot the low round at 64? Did Haas employ a different strategy when the same player shot 77 on the last day? I understand that over time the results (particularly the lack of an ACC title are gauling), but if you have ever played golf, it's really weak sauce to blame the coach for individual players shooting their worst round by 16 shots on the last day. That's just the nature of the sport.
As for the tradition of WF, yes WF has an amazing golf tradition, and that helps with recruiting, but WF built that tradition at at time when only a handful of schools even attempted to compete in golf, and when there were no limits on scholarships. The landscape of the golf has changed. Schools like Clemson, GT, FSU, Bama, Auburn, OK State, Texas Stanford, now are all in on golf. Golf was at best a niche college sport in the 1970s and 1980s when WF dominated. Also, don't discount the fact that WF doesn't have its own golf course. In the 1980s and 1990s, Arnold Palmer led an effort to build an elite WF golf course, and the school couldn't raise the funding. WF has amazing practice facilities and plays at awesome course all of over the country, but it doesn't help that there is no WF golf course.
