There aren't many tougher jobs in sports than being the head coach of an NBA team.
Unless you're part of the truly elite fraternity of signal-callers, your job is in a constant state of insecurity. Coaches are fired with reckless abandon, especially as the signings get more and more risky.
Of the 30 head coaches during the 2012-13 season, 13 weren't permitted to return to their previous team.
That list includes guys like George Karl, who won Coach of the Year, Lionel Hollins, Doc Rivers, Byron Scott and Larry Drew.
That alone should tell you what a high-pressure job it is. And yet, there are still a select group of coaches whose situations make their jobs even tougher.
Seven of them stand out this year, and only four are joining the ranks of NBA head coaches for the first time.
