Let's examine the 3 possible outcomes.
>day 1 Cody wins the tag team
>day 2 Cody wins a good clean match
A boring outcome but the bloodline plunges into irrelevancy, so it's welcomed. Cody is solidified as the megastar, but a possible angle for him going heel opens, as the wins go to his head and he grows arrogant. Seth vs Cody later, perhaps?
Option 2:
>day 1 Cody loses the tag team
>day 2 Cody wins despite bloodline interference
Best outcome, mega pop at the end. Everyone would love to see this. Cody rises as a true american hero surviving against all odds and defeating evil.
Option 3:
>day 1 Cody loses the tag team
>day 2 Cody loses to Roman, badly
The Bloondline's stale reign of terror continues, Cody is humiliated and never gets a shot at the title.
Bonus option 4:
>day 1 Cody wins the tag team
>day 2 Cody loses the match because of Bloodline cheating and ignoring the rules
The most unlikely outcome but the Bloodline will generate more heat. And is also kinda predictable? Worst possible option.
My prediction is that Cody will win. If he loses, meh.
