If the fight happens and Cruz is 100% or close to it he wins, TJ is great but Cruz is not flat footed and easy to hit like Barao. TJ would have a very hard time finding Cruz...and I do not think Cruz would have any issue's hitting TJ in return.
Cruz has the most depressing story in MMA atm, was at the top of his game...then injury after injury kept him from being the GOAT in that division...I really hope he comes back to his old form...but hard to say.
