Chicago ? Chicago Bulls general manager Jerry Krause resigned Monday, citing health problems, after helping build the most dominant NBA team of the 1990s and then struggling to rebuild.

With Krause as GM, the Bulls won six titles behind the play of Michael Jordan. But Chicago has bottomed out since Jordan left after the final championship in 1998.

At 27-50 through Monday, Chicago will finish with a losing record for the fifth straight season.

“The rigors and stress of the job have caused me some minor physical problems in the past few years,” Krause said in statement.

The 64-year-old Krause, the Bulls’ GM since 1985, did not elaborate on his health problems.

Just as the two-time NBA executive of the year was credited for finding players to complement Jordan — a player he did not draft — Krause was criticized for breaking up the success.

He alienated coach Phil Jackson, Jordan and Scottie Pippen, often over who should get credit for the championships. When Jordan retired before the lockout-shortened season of 1999, the dynasty crumbled.

Krause emphasized in the team statement he was not retiring.
