Something was said by a writer that it has to do deeply with the feeling of the "warrior without a master" mentality of the Ronin name. Meh. I think that nixes Hawkeye according to that note. It could be Kole, since he's not following Black Panther anymore, but again. . .it comes off sort of lame duck.
