'Criminal Minds': Could the BAU Have Done Anything to Prevent Barnes from Splitting up the Team?

Prentiss was already suspended from active duty before "Annihilator" on Criminal Minds, but that was nothing compared to Assistant Director Linda Barnes' moves by the end of the episode. She may not have been able to disband the BAU like she did the IRT, but she could "help restructure" the "crown jewel of behavioral profiling" -- and she did.

Prentiss and Tara were being reassigned within the FBI. Reid was going to be a full-time professor. Rossi was forced into retirement. Simmons and Luke were to remain at the BAU. Garcia's loyalty to the team was appreciated, but she was getting a fresh start in a new department. J.J. was made conditional unit chief of the BAU, and she'd have to run every single decision by Barnes. ???
