I said this last year
I thought they were gonna turn him then but saving it until Mania was a good call. I think it was unfair to expect them to put on a 30 minute face vs face classic when the build was a friendly rivalry where they didn't put hands on each other
I felt like the Mania match was the appetizer and the next match (their 3rd at 1 each with Naka playing heel this time) they'll go all out. I think Nakamura expected the match to go in his favor again and underestimated AJ, hence why he snapped and why he toyed with him during the built.
