For the following five coaches, the 2012-13 NBA season represents a make-or-break year. These coaches are in situations where their teams must win now, or they'll face the genuine prospect of losing their position on the sidelines.
It's true that a case can be made that every coach in the league is under considerable pressure. As leaders of their teams, they are ultimately responsible for the on-court performance of the roster with which they have to work.
However, the coaches who are working on borrowed time have found themselves in unique situations.
For some, they suddenly have found themselves at the helm of a team that is expected to be dominant. Some are the leaders of teams that have made significant strides this offseason. Others are working with contenders in the making, while another is entering the final year of his contract and needs to significantly change the fortunes of his team.
The varied situations that these coaches find themselves in shows how cut-throat coaching in the NBA actually is.
So, with that said, who are the five coaches operating on borrowed time this season?
