#1 Drew McIntyre
The WWE have been grooming Drew McIntyre to be a main event heel since the point he got to the main roster, and with Seth Rollins now reigning as the Universal Champion, it's only a matter of time. The Scottish Psychopath is the perfect person to have in the main event: he has the looks, he works hard and most of all, his intensity is unmatched, and in terms of a locker room leader, you couldn't find anyone better.
10 years ago, Vince McMahon proclaimed that a young Drew would be World Champion one day, and although they stuffed up his first run within WWE, he's come back better than ever before. It may not happen until SummerSlam, or potentially even later in the year, but by the time 2019 is finished, expect to see McIntyre at the top, and with all types of young babyfaces coming through the ranks, his reign could certainly be a fun one.
