Martinez has had 3 seasons and is nowhere close to breaking into the top 4 and then building on that, yet you want to persevere with him. Which is quite a contrast to the example of Kerr that you've provided.Disagree there...if you are the right man for the job. Steve Kerr who is the head coach of the Golden State Warriors in the NBA had zero head coaching experience before being hired at the beginning of last season. He led them to the NBA title in his first season. He has them on pace to have the best record the NBA has ever seen this season.
