Yep.
The way I see this fight playing out is Conor will come out really strong, probably floor El Cucuy with that left, maybe even a couple of times. He will hurt Tony and have him in some trouble early.
BUT - Just like with Nate, he's not going to follow him to the ground, and risk getting subbed.
Tony then recovers, and starts to wear McG out against the fence and with the grappling (snap-downs, threats of D'arces, etc).
By the end of round two, Conor is already gassing.
Round 3, he is taken down, GnPed on for a bit, then subbed.
