#3 WWE already has Superstars like Braun Strowman and Drew McIntyre
Alright, frankly speaking, the majority of Brock Lesnar's appeal comes due to his great success in the UFC and his larger than life stature. Well, although the WWE has no shortage of big guys, a big guy with charisma and personality has always been hard to find.
However, the current RAW roster consists of not one, but two big guys with both charisma and personality -- Braun Strowman and Drew McIntyre. Furthermore, both The Monster Among Men and The Scottish Psychopath are incredibly over with the WWE Universe today!
I'd also like to add that unlike Brock Lesnar, who is a part-time WWE Superstar, both Strowman and McIntyre perform for WWE on a full-time basis. Currently, Strowman is 35, whereas McIntyre is 33 years of age - and if the WWE doesn't put the title on them now, they may never be able to capitalize on the current buzz that these two gentlemen have been generating as of late.
