The two members of the front office were apparently face-to-face during the middle of a sit-down meeting "with the possibility of a confrontation," according to Shariff. The reason for the blow-up is not known, but there has been tension between the pair since last offseason.
The latest situation between Ryan and Daniels involved the firing of bench coach Jackie Moore. Moore was hand-picked by Ryan to replace Art Howe as the team's bench coach, but Daniels wanted to replace him last season. The Moore situation became a "flashpoint of front office tension," notes Evan P. Grant of the Dallas Morning News, and could have boiled over into the meeting.
Moore made it clear that he thought his firing was related to his and Ryan's relationship; he discussed the reasons behind his firing with Todd Willis of ESPNDallas.com, telling the reporter, "You look for reasons and I haven't found any, other than me being a Nolan guy."
