The first reason is that Nash is a superstar. As an athlete, he is very popular. He is famous for playing small balls in the sun and Mavericks. This is what Nash is good at, plus his personal ability and ball dealer, the Nets are very confident that he can become a qualified coach. What's more, he once studied in the champion warriors and served as an assistant coach. Referring to the growth track of Warriors coach Cole, Nash has a good chance to become a famous coach. Although his weakness is that he can't defend the college entrance examination team, this weakness doesn't prove that Nash has no defensive experience!
The second reason is actually a problem within the team. Durant and Owen's dual core can actually affect the existence of Nets management. Owen 20 15 trained with Nash and had a good personal relationship. Durant had a mentoring relationship with Nash when he was a warrior. Only when they are satisfied with the selection of coaches for the Nets can the new coach gain a firm foothold. Nash did lead the team to the Eastern Conference finals in his first season. If it weren't for Owen's injury, it is estimated that the championship would be the Nets'.
The third reason is Nash's own traffic. As a legendary superstar, he can help the Nets in many aspects, such as attracting stars to join, using contacts to sign players, locker room leaders and so on!
The above reasons are the consideration of the Nets. Of course, all this must be based on team performance. If he doesn't behave well, Nash will have to finish class.
