#3 Roman Reigns return against McIntyre

We don't really know yet the direction which Drew McIntyre's assault on The Shield members is going to take. He's taken down Roman Reigns and then dominated Dean Ambrose in their match.
He's even called out Seth Rollins on the next week's edition of Monday Night Raw. Does it mean finally a Championship push for Drew and could we actually see Drew entering the championship picture at WrestleMania (considering Brock is hardly around)?

Or does this mean a feud between Drew and one of the members of the Shield at WrestleMania? Right now it's the second scenario that seems more than likely and if that is the case then Roman Reigns needs to make a return because if these two collide it would be one of the better matches on the card and should be given proper airtime to gain some momentum.
