Not enough options really. I guess it would have to be Ward- Brand, followed closely by Canelo-Khan and GGG- Brook. I don't rate Haye and his circus act to give him a vote. I also see no reason to have Wade on there, he was a mandatory. A miss match must be picked without outside pressure, and must not have a belt, imho. Same reason why I'd give Canelo a pass for fighting Smith, despite the chasm in class.
Private poll is fail...Now all of he "big fans of Golovkin " are going to come en masse and vote for Wade.
GGG-Wade, followed by Haye-Gjerjaiajejjajajerifaja, Ward-Brand, Canelo-Khan and GGG-Brook. GGG-Brook not really a mismatch though. He'd last as long as other middleweights
