You are correct that recruiting and developing NBA talent is a positive. One conclusion is Prohm will bring even more NBA talent to a P5 conference school. If that is the outcome the Cyclones will do well. An alternate conclusion is, playing for a perennial conference winner, Murray State, that captured their 24th Ohio Valley Conference regular season championship is a draw for NBA talent. If everyone’s first choice is to play in a P5 conference NDSU and UNI wouldn’t get enough talent to compete with BCS schools. Some people would rather be the big fish in a small pond. That begs the question, should Prohm’s record be better in the Ohio Valley Conference with NBA talent?This seems an odd post to me. So you are saying that his proven track record of recruiting and developing NBA caliber talent is a red flag? Irrespective of your conference, NBA talent is NBA talent. The point is being able to identify great players, recruit them successfully, keep them at your school, and develop them by putting them in the best positions for success. The fact that he's done that AND sent some to the NBA is a good sign.
Of the leaked candidates Prohm is my preference. His style sounded most like Johnny and Hoiball. He graduates his players and has a known coaching style and demeanor. The only thing that looks close to cautionary is did he perform up to the level of talent on his teams.
