The job security of Philadelphia 76ers head coach Brett Brown has been a hot topic this season. If you ask Sixers General Manager Elton Brand, he'll have a simple answer.

It has been a largely disappointing season for Philadelphia. After taking eventual champions Toronto Raptors to seven games in the second round of the playoffs last season and then signing All-Star big man Al Horford, expectations were high for the Sixers going into this season.

And while they are still in the thick of the Eastern Conference playoff race, perception of the team has turned sour quick. Through 52 games, the Sixers sit at 31-21 as the conference's sixth seed, just half a game behind the Indiana Pacers.

Moreover, the team has lost four of its last five games, three of which came against opponents they could face in the Eastern Conference playoffs down the line.

Preseason betting odds had the Sixers as the team with the fifth-highest odds to win a title, but as the season moves into into its second half, the team simply isn't there yet.

In his six previous seasons as Philadelphia's head coach, Brown has made the playoffs two times and has amassed an overall record of 178-314.

Next up, Brett Brown and the Sixers have a three-game home stretch against the Chicago Bulls, Los Angeles Clippers and Brooklyn Nets.
