While Drew McIntyre, Ricochet, Braun Strowman and Baron Corbin will feature in the men's MITB ladder match as Raw's participants, the likes of Finn Balor, Andrade, Randy Orton and Mustafa Ali will feature as the blue brand participants. However, a classic 4-on-4 tag team matchup should be on the cards on the upcoming episode of Raw.
Yes, given that 4 Raw and SmackDown superstars can now move between brands each week for a one night only appearance (thanks to the Wild Card Rule), WWE could have the SmackDown's participants for men's MITB ladder match on board for this Monday night on Raw.
This could then lead to a classic 4-on-4 tag team match up between Team Raw and Team SmackDown for the main event. While this would not only be a fascinating battle, but it would also set the tone for MITB.
And given the fact that it's every man for himself at MITB, plus the massive egos, the match is bound to turn chaotic sooner than later, leaving only one man standing tall (Braun Strowman, maybe, reverse Psychology of WWE) over the rest.
