I will give an answer; he flat out gets it done. I have watched Hightower work games for years in person at the Big Ten Tournament every year since 2000. I can tell you he knows how to handle players, coaches and works with his partners well. I agree that his mechanics are not to the letter (but who is that is at that level if you want to be honest), but he flat out can referee and has the respect of all the coaches. Now you might not agree but no one asked you.
Peace
