He rolled quite a bit with Miranda and Grove, neither the grappler Fitch is and he didn't get a sub in a full 3 rounds.
I agree Fitch should stay away from too much ground game, but it isn't automatic that Maia would find a sub.
True, but there's something about this 170lbs Maia that I find downright scary, perhaps its the crank he put Story in that freaked me out, I dunno. But Fitch should keep this fight standing. If Erick Silva can get your back, Maia will put you to sleep.
