I don't see the speculation, or the impression, that this will lead to a Cesaro face push.
In order for WWE to create another Daniel Bryan like situation, they'ld need a face with an organic connection to the fans. That's what Daniel Bryan has that few others do. While Cesaro has made an impression on the fans due to his swing and his strength, he's yet to really do anything to get the fans behind him, rallying for a push. The idea that handing out signs could create a push for Cesaro is essentially telling the fans who they should cheer for. When I say Bryan's connection was organic, I mean that the fans were the ones who essentially dictated the terms. They told WWE, of their own volition, that they wanted to see him pushed. And they responded to his push-and at a time, lack thereof- in their own unique way.
I honestly thought all of this would lead up to Cesaro winning the IC tournament, and Heyman being able to boast that he's created two out of the last three IC Champs. Cesaro takes exception, turns away from Heyman, and is 'punished' by Paul in the same fashion that CM Punk was. He has to deal with Heyman's beast, Brock Lesnar.
The fact that Cesaro is even being considered for a match with Lesnar is a huge honor for him, but we'll see how that goes. I think fans have rallied behind him and his wrestling abilities. I think fans love to see the swing, and they love to see him hit the Nuetralizer on men much bigger than him. But that they're even close to invested in him the way they are in Daniel Bryan? There's nothing WWE can do to force the fans hands. They can push him as far as they'ld like, but the fans themselves will dictate what they want to see.
As for a match with Lesnar, the fans are going to have to get behind Cesaro in a major way in order for that to happen. In taking a look at Lesnar's opponents since returning, you've got John Cena, HHH(thrice), CM Punk, Big Show, and The Undertaker. Other then Show, those are all top-of-the-card type of guys, and Lesnar dispatched with Show in less then 4 minutes. I'd argue that his match with Show was nothing more then a show of dominance by lesnar to make him look like a threat to the streak.
Turns out he was.
To even consider Cesaro as a possible opponent for Lesnar, he'ld need a mega-push along the lines of winning the WWE World Championship, without Heyman by his side. Further, the fans would have to embrace Cesaro winning the championship, and moreso, they'ld need to be angry to see him lose it. Perhaps in a screwjob regarding Heyman and Lesnar. Something that would infuriate the fans enough that they'ld want to see Cesaro get his hands on Lesnar at WM 31, in fact. Right now, WWE has plenty of time for that, however.
It's almost a year until WM 31, so taking it slow with Cesaro would be the best approach. Have him win the IC title, and progress with Heyman by his side. However, just as they did with Punk, have Heyman overshadow him and take credit for his success. If he snaps- like Bryan did on Bray Wyatt - and the fans respond favorably, then consider giving him that huge push to be Lesnar's opponent.
The problem with Cesaro is this: He's not shown decent mic skills, and he doesn't have much charisma, either. He was able to get over being paired with Zeb Colter, who is gold on the mic. Then he was given some long matches against great opponents, and either held his own(John Cena), or flat-out beat them(Randy Orton). The swing has also been a big factor in getting him over, especially since he's begun wrestling like a face.
But he's going to need more then that. Especially once he breaks free from Paul Heyman. He's going to see he can hang on the mic....and that the fans can get behind him as well.
First stop, I believe? Winning the IC Tournament and then, the championship from Big E. Let's see how the fans react to that.
