I told you previously that I'm confident Naito was supposed to win last year, but they flipped the outcome due to Omega's tournament performance. So, his beating Okada only to lose a G1 Final rematch was precisely what I expected.
Okada and Omega are both in B. My presumption is that Omega wins that non-title bout, and Naito wins Block A and then the tournament by defeating Omega, who is worn out from the Okada match.
The other thing that they may be doing here is Tommy Dreamer vs. Raven, where one guy never can quite beat the other.
