Big GGG fan but can't help but root for Brook!!

GGG is one of my favorite fighters today. I love offensive fighters and GGG is the best at the moment so I automatically became a huge fan after watching him demolish everyone on his path. However, I just can't help but root for Brook. Brook didn't have to take this fight because although it will be his biggest payday, I can't imagine it being astronomically more than his current highest payday given that although GGG is a BOxing Star he still isn't mainstream. It takes colossal balls for a WW to go up 2 weight divisions against the best MW, who happens to be a brutal puncher with boxing IQ. Other top MW's are making excuses not to fight him. In my time of following boxing since 2002 this is probably the most courageous risk a fighter has taken. Yeah we've seen a fighter move up two divisions and win (Pacquiao-De la hoya) or fighters beating much bigger men but those bigger men were cherry picked. Roy jones fought the weakest HW champ, Pacquiao fought a past prime Margarito, Mayweather fought past prime Oscar etc. GGG is in his ****ing prime. It's crazy to me. If Brook pulls this off :hail::hail:
