Yes these hirings are common. Michael Porters father was hired as an assistant a few years ago, the Mobley Bros father is an assistant at USC. Back when I was in HS, Kevin Mackey hired Leo Papile as an assistant at Cleveland State to bring big man Eugene Miles, one of the countries top recruits, and half of his Boston AAU team with him. There are many more examples every year of this and it goes back decades as far back as Danny Manning’s father being hired at Kansas to bring Danny with him......very common.This is a nothing story. Mike Boynton hired Cade Cunningham's brother as an assistant and guess where he went? Back in the day, Bill Self hired Mario Chalmers' father as an assistant and guess where he went? It's been going on for years.
In one of the most blatant cases, Lamar Odom’s high school coach was hired as an assistant at URI then promoted to head coach in the hopes he could convince Lamar to stay. He didn’t.
