#2. Braun Strowman - An unlikely dream match for Daniel Bryan
Braun Strowman and Daniel Bryan have either been on different brands or have been kept apart when they were both on SmackDown. Over the last few years, Strowman's biggest feuds have been against big men of slightly smaller stature.
It's not often that WWE books The Monster Among Men against a superstar of Bryan's size, but it would make a great SummerSlam match. The great part about events like SummerSlam is that it's not always about match quality. A spectacle is what fans like to see, and presenting Daniel Bryan as an underdog against a bigger opponent might result in a great crowd reaction.
Braun Strowman doesn't look like he's going to find WWE Championship success anytime soon on RAW despite his presence in the title picture. With at least two or three other stars ahead of him in the pecking order, a non-title feud against Bryan would be perfect for SummerSlam.
A good stipulation that gives Daniel Bryan a chance might result in an unlikely classic.
