Frank Vogel is "coaching for his job" despite a 56-win season, according to sources.
The Indiana Pacers began the season with a 40-11 record, but went just 16-15 during the rest of the season.
Larry Bird will ultimately make the decision about Vogel at season's end.
During the last week of the regular season, though, Bird told local ABC affiliate WRTV-6 that "I back Frank 100 percent."
Vogel received a two-year extension during the 12-13 season that keeps him under contract through 14-15.
Chris Broussard reports that the Pacers have missed the locker room presence of Brian Shaw, who often played the role of "bad cop" to keep the locker room from imploding.
