It seems to me this forum is composed of people with a diversified range of thinking. So it isn't all that difficult to extrapolate that recruits also view the world differently from one another.
Factoring this in I would say it could help, it could hurt or it may be inconsequential.
It would hurt getting any recruit who wants assurance the team he is heading to will have the same coach four years from now should this recruit stay in college for four years. Wasn't this argument made in the latter years of JC's career? It could help if a recruit believes that a coach with NBA cache increases the chances of this recruit to get into the NBA. And it would be a non factor if a recruit felt the future has too much uncertainty to factor this into the equation or is confident in his own potential to be overly concerned about this factor.
Personally I felt KO already had the cache based on his NBA career and how much praise he had received from NBA coaches and players. Therefore
the net consequence of these rumors/commentary about him someday becoming an NBA coach is an overall negative imo particularly if KO prefers to be a UConn legacy. It could turn off one or more of the recruits who want to come to UConn and want stability and most likely have very little impact among recruits who already factored KOs NBA cache.
Many people lack either the time and/or the ability to discern if statements are credible or important. And there are people who chose to exploit this. The best way to do this is to issue statements repeatedly and issue it from many sources. It becomes the default for many of us to believe something is a fact when this happens. After all it resonates with the way we learn things. Think about the way we learn the alphabet, colors and numbers as infants and toddlers from adults, the authorities of our childhood. This method is sometimes transferred to the way we process information about issues.
This is an overly simplistic explanation about learning. But I believe it has some merit and it is the basis for why I was upset with the recent episode of tweets by a cadre of reporters. Although I must admit I let my emotions get the better part of me when it was happening. Thanks @8893
