I think he's a Z, not an X. He excels at creating separation to make catches, while MT couldn't get much separation and had to body his way to catches.
We didn't complain about MT never getting much separation and mostly being fed by great accuracy from Drew, did we?
Different types of receiver, both can be great. No need to force the comparison IMO.
i think you all just witnessed elite CB play, look how Alonte mirrored Olave. Id say that also due to familiarity more than Olave can beat press man coverage. (at least i hope not!)
