There's a long history of green fighters beating experienced men that were even better than them. We revere the older fighters for what they have done meanwhile try to conceive reasons to deny the newer fighters an opportunity to achieve. There is almost no chance Thurman will be as good as Marquez or PAC but he is big, young, and strong. These factors give him a chance against these versions of Marquez/PAC. I'd even pick him with relative confidence against Marquez now and Marquez is easily my favorite of the three. Eventually with all youth is served.
