Three.... if I haven't missed any.
None of any consequence, and none have been on the job long enough to fairly evaluate... but if one had to "grade" them they would either be Incomplete or Lousy:
The previous Men's Soccer Coach retired (at least I think that is how it was announced at the time - I don't follow closely enough to know what he did after leaving PSU)
1) Jeff Cook - the Men's Soccer Coach. Just completed his first year. They had a losing season, and dropped out in the first round of B10 Tourney.
Two Coaches that had to be hired after they canned the old ones for "abuse" complaints from athletes - - - - - that Charmelle Green FUBAR-ed.
2) Sarah Brown - Girl's Gymnastics. She's a couple years in. Last year was one of Girl's Gymnastic's worst years ever.... 7th at B10s
3) Jeff Kampersal - the Girl's Hockey coach, he is 2 or 3 years in….. Girl's Icers have been consistently Blah
Gondak, the track coach, was already serving as the interim head coach when Sandy arrived. He, technically, became the "permanent" head coach after Sandy Baby got here.... but one would be hard-pressed to claim she "hired" him.
