2 WWE Superstars who should challenge Brock Lesnar at Royal Rumble 2020 and 2 who shouldn't 

#1 Shouldn't: Seth Rollins

Rollins and Lesnar in action

There is no denying that Seth Rollins has had a memorable year, as he has achieved a number of incredible feats. From winning the men's Royal Rumble match to grabbing the Universal Championship twice, both times from Brock Lesnar, Rollins has done it all. Furthermore, he recently turned heel, which was a brilliant move to reinvent himself and rekindle the reactions from the fans.

While Rollins has been the face of the Red Brand, he is certainly not the best pick for the brand's champion, as they already had a lengthy feud. That's not the only reason he shouldn't challenge Lesnar.

After joining up with the Authors of Pain, Rollins is looking like a serious threat as a heel, and he needs more time before entering the WWE Championship picture. If Lesnar holds the belt for a long time, he might collide with Rollins in the latter part of 2020. Right now, however, while he is feeling much fresher as a heel, it's simply too soon.
