It wouldn't hurt for The Rock to appear in a few cross feud tag matches than inevitably ends in a DQ.
Just shake off the rust, get himself reacustomed to the timing of moves. He's just beyond terrible at this point in-ring wise. Even worse than many Tough Enough tryouts.
As for gassing out early in his matches, I'm honestly torn between it being a stamina issue or he's just overselling. Even back in his prime he always acts like he needs to take a breath even in the middle of his matches.
