#1 Paul Heyman turns on his client before the cash-in
When Paul Heyman stepped out to deliver his promo on RAW, I'm sure that a lot of people assumed it wouldn't be as the advocate of Brock Lesnar. The fact of the matter is that Heyman is an important backstage figure now as the Executive Director of RAW, and that is a role that he could potentially own.
And the fact that he's the advocate for Mr. Money in the Bank, Brock Lesnar, could be a detriment to this role. I'd rather have him as an on-screen authority figure at this point than as the mouthpiece for Brock Lesnar.
And because of this, I wouldn't mind seeing him turn at Extreme Rules before Lesnar cashes his contract in. Maybe he could associate himself with Lashley going forward based on the momentum Lashley has from squashing Rey Mysterio.
We could see Lesnar vs. Lashley at SummerSlam then.
