#2 Brock Lesnar: Former WWE Universal champion (Raw Brand.)

Though he recently lost his title to Roman Reigns, Lesnar was champion for most of the summer and still deserves consideration on this list.
Brock's Grades:
Top name doesn't want to enter the WWE Hall of Fame. More details HERE.
Dominance: Brock held the title for most of the summer, however he had only one defense in that time, and he lost the belt. Grade: D
Contenders: Brock had only one contender, Roman Reigns, who is a top-tier talent. However, it was only one challenger for the entire ninety plus days of summer. Grade: C
Talent: Brock has slowed down from his triple powerbombing days, but he still can work a decent match with the right opponent. Grade: C
Popularity/Marketability: This is a double edge sword. On one hand, Brock's enormous name recognition and appeal is likely to get casual and non-wrestling fans to tune in to his infrequent contests. On the other, the more dedicated wrestling audience seems to resent him. He splits the difference with an average grade. Grade: C
Overall Grade: C- Brock's lack of title defenses and the fact he lost to his sole contender lower his grade, as well as his polarizing effect on fandom.
