3 reasons why Seth Rollins became the number one contender for Brock Lesnar's Universal Title 

#1 To book a better feud with Brock Lesnar

It should be better at SummerSlam

Seth Rollins has been enjoying a spectacular run this year. The former Universal Champion has rejuvenated his character in the recent months and he is certainly the biggest full-time Superstar of the Red Brand. Meanwhile, Rollins has also been the primary opponent of Brock Lesnar this year.

Rollins had a great start of the year when he won the Royal Rumble Match. As a result, he was given a choice to pick a World Champion and he chose to challenge Brock Lesnar at the Grandest Stage of Them All. In my humble opinion, the build-up of their WrestleMania clash wasn't remarkable as Brock Lesnar didn't appear on RAW regularly. Lesnar had limited dates and he didn't show up until a few weeks before WrestleMania. Since the Beast was absent for weeks, the rivalry didn't get the opportunity to reach the true potential.

Since Rollins will be facing Lesnar at SummerSlam, they could tell a better story this time. The feud could become more interesting if Lesnar shows up regularly. After winning the Money in the Bank briefcase Lesnar appeared on RAW for three consecutive weeks, hence, it can not be ruled out.
