i sincerely doubt we will see Glover throwing up armbars and triangles. Arona was a good ADCC competitor and he is pure top game, more then likely Glover is as well.
He's got a punches chance against Jones and that's about it. though he probably won't be getting ragdolled early as his wrestling is pretty good so there's more of a chance for it to happen.
Disagree...Glover looks fairly fluid on the ground with his movement I fully expect him to have game on his back.
