#3. The Undisputed Era Vs The Shield
Many fans might say that this rivalry will not happen, but this is a real possibility. Dean Ambrose recently returned from injury and all the members are on Raw. The second-last time we saw Dean Ambrose, he was a part of the Shield. During 2013-14, The Shield was the best act and team in WWE. But the years have gone, and 2017-18, Undisputed Era has proved themselves as the most dominant group in WWE.
The Shield will be back this year and Undisputed Era might also be on the main roster. Undisputed Era Vs The Shield is a money match and a guaranteed classic. While Roman Vs Cole was unpredictable, this rivalry should end with Undisputed Era standing tall over Shield.
To add more to the mix, WWE can book it as Winner takes all for Universal Championship held by Roman Reigns and the Raw Tag-Team Championship held by Ambrose and Rollins.
