Well yeah, there's that. Should never hold a prospective hire's health against them but repeated bouts of overstress might be something to consider when hiring for an ultra high stress job. Could be argued that at least she's known to step away before things got out of hand.
So maybe GG is a short term (3 or 4 yrs) bridge coach who rights the ship and begins to restore glory before the real star hire takes the helm. I always thought GG was a pretty tough coach, and as I remember, not afraid to have strong and pointed conversations with players during games. She had a bit of an edge which I hated then, but kinda like now. I remember a GG interview the day after her Duke team pulled a monumental Regional tourney upset of the LVs in 99, rudely ending the careers of 3 time natty champs Chamique and KJH. GG said haughtily she didn't really consider it an upset at all, she kind of knew it all along. Took me years to forgive her! Truth is, back then, she was a very good coach.
