IF Billy Taylor is successful as head coach at Elon or wherever else he may land in the next 7 years or so, he's by far more qualified than Connor, Gatens, or Eldridge IMO if you keep it in the Hawkeye family.
He's actually had some pretty good success turning programs around to be in the upper tier of their respective conferences including one NCAA tourney birth at Lehigh. The only one of the above to have head coaching experience and has had experience as Iowa assistant for 6 seasons. He's from the Chicago area - a key recruiting area for the Hawks and also played big time ball at Notre Dame.

I believe Taylor was instrumental in bringing in some quality Iowa recruits too. I certainly stand to be corrected on this as I really don't follow recruiting that closely - especially at the assistant coach / lead recruiter level.
