One staff member described the atmosphere as “icy… you could feel something was about to blow up.” Another noted that Brown rarely issues ultimatums, which makes this moment even more alarming. Tatum, meanwhile, is reportedly trying to play peacemaker, but those close to the team say the situation could “turn nuclear” if negotiations with the unnamed player go any further.
