#2 The tag team title picture is already very busy
And speaking of The New Day, I have to say that they're in the other hot feud on SmackDown at the moment with The Miz and the returning John Morrison. Anyone who's followed Morrison during his time in Impact Wrestling knows that he hasn't lost a step but it was great to see the WWE Universe in shock and awe as Morrison demonstrated just how good he truly is.
My point is that The New Day seems to be in the tag team title picture right now with Miz and John Morrison.

So, there would have been no point in bringing back The Usos as tag team competitors considering the fact that The New Day are babyfaces and also, engaged in a feud. WWE did the right thing by having Roman Reigns team up with The Usos and enter the other big storyline that's happening on the blue brand.
WWE is all about telling stories and they're telling a fun story at the top of the card with Roman Reigns and King Corbin, with the supporting cast also having the limelight shone on them, in the process.
