Jameel McCline is an underated fighter who beat Grant, Briggs and Whittaker 3 top 10 ranked fighters whilst Lewis was champ without barely losing a round. Unless this MaCline you speak of is another fighter?
Nobody in the post Lewis era in underrated... And McCline was way over weight when he took the Peter fight on two weeks notice.. The decision was razor close.
I'd take Brewster over Ibragimov. Brewster's impressive knockout wins over Wlad Klitschko, Luan Krasniqi and Andrew Golota in title fights were better wins than Sultan decisioning Briggs and a 45-year-old Evander Holyfield. And Ibragimov's loss to Wlad was so one-sided it seemed like Sultan quit trying to win a quarter of the way thru and just wanted to go the distance.
