2 reasons Brock Lesnar should cash-in his Money in the Bank contract on Seth Rollins and 2 he should cash-in on Kofi Kingston 

#3 Cash-in on Kofi Kingston - Make SmackDown feel like the 'A' show

SmackDown needs Lesnar

Believe it or not, but fans always tune into WWE programming whenever it is announced that Brock Lesnar is going to show up. This time he has the Money In The Bank briefcase by his side as well, so he can show up on Tuesday nights and tease cashing in every week. Kingston does not have any rivals on SmackDown right now.

Until and unless a New Day member turns on him, nobody is going to be invested in the WWE Championship feud. Sure, he had a decent rivalry with Kevin Owens but SmackDown needs something big before they move to FOX. Brock Lesnar can help the blue brand's cause and it will be great for Kofi himself if WWE books a feud between him and Brock Lesnar. It will establish him as a grander star.

Brock Lesnar cashing in his MITB contract on SmackDown will boost the ratings and also keep the fans hooked.
