First of all, I like Karev - I have nothing against him, he is portrayed to be a fine surgeon.
In saying that, Miranda Bailey was a vital influence in M.A.G.I.C’s growth as doctors. She is the heart of the hospital, when Bailey says jump, you jump! As the characters developed, it is argued that Bailey pulled the short end of the stick. And in all honesty in the last few seasons she has made irrational and unprofessional decisions, which question her leadership & characteristic profile. But that aside, the good Dr. Bailey has done for the hospital, staff, patients over the last 11 seasons makes her an exceptional candidate for the board. She is a visionary amongst surgeons has can make change happen easier than most.
She deserves to be Chief of Surgery if not made a board member.
She is owed something extraordinary for being an extraordinary individual
