It is probably the easiest route for Mitchell right now to get a world title. Demarco isn't all that. He might go to Mexico and milk the title though?
I don't think Mitchell has the power to stop DeMarco inside schedule, and I don't think he has the tools to dominate to the same degree that we saw Jorge Linares dominate for 10 rounds. DeMarco will have success, and it's just a matter of whether or not Mitchell can take what the Mexican has to offer. I'm undecided, but it'd be a more competitive fight than Duke would have you believe.
