#1 Worst: Not building a new star
I guess I get why Brock Lesnar made a return and I get why he became Mr. Money in the Bank as well. However, what I do not understand is WWE's reluctance to build a new star.
They have the most stacked roster that the company has had in its rich and illustrious history. There will come a point when Brock Lesnar retires and wants nothing to do with the company anymore; when WWE will have a massive void to fill.
Instead of grooming new stars and awarding them opportunities, WWE is content to keep giving chance after chance to Lesnar. I loved his interference and also the surprise element, but truth be told, I would have preferred to see someone like Drew McIntyre claim the prize.
I particularly hated the fact that Ali just froze on the ladder when Brock Lesnar's music hit.
