When Brock Lesnar returned to WWE the night after WrestleMania, the wrestling world was abuzz regarding what he might do. Lesnar went on to lose his first match back to John Cena, however, and has lost most of his momentum, so I consider him a lock to win against Triple H at SummerSlam.
Usually, when the WWE brings back a past superstar, he is the one who is put over, but Lesnar put Cena over instead. A lot of people had a problem with that, and I wasn't a big fan of it either.
However, the WWE can still turn things around if Lesnar beats Triple H at the second-biggest pay-per-view of the year.
The WWE is reportedly paying Lesnar an awful lot of money to be a part-time performer, so it is crucial that he is utilized to the best of his ability moving forward. Lesnar lost a lot of steam by losing to Cena and subsequently disappearing from WWE programming, but the company has a chance to right a wrong by putting him over Triple H.
There is a school of thought that Triple H's supposedly massive ego won't allow Lesnar to beat him at SummerSlam, but that is a played-out point of view. Triple H has lost to The Undertaker at WrestleMania the past two years.
Also, seeing as how Triple H has a hand in business decisions within the company, I'm sure he fully realizes that having Lesnar win would be much more lucrative for the WWE.
After the match at SummerSlam, Lesnar probably only has three matches left at the most, so you can't have him losing his first two. He may have one at Survivor Series, I could see him entering the Royal Rumble and he'll obviously have a match at WrestleMania.
Lesnar desperately needs momentum and beating one of the biggest superstars of all time in Triple H would give him plenty.
On top of that, I feel like a match between Triple H and Shawn Michaels is being set up for WrestleMania as well. In order for that to happen, though, Triple H would have to lose on Sunday. Lesnar kayfabe broke HBK's arm with a Kimura lock, and although there is uncertainty regarding Michaels' status as Triple H's corner man, I believe he will be there at SummerSlam.
The events that occurred on Monday were clearly meant to foreshadow something bigger. Michaels talked to Triple H on the phone about how Lesnar was Triple H's battle and how he didn't want to be a part of it.
Despite that, Michaels got caught in the middle and was ultimately attacked by Lesnar and left crippled.
With that in mind, I anticipate an HBK heel turn at SummerSlam. Triple H will appear to have things well under control, but during a period of time in which the referee is incapacitated, Michaels will shockingly hit Triple H with Sweet Chin Music and Lesnar will end the show standing tall.
The next night, it can be explained that Michaels is tired of always having to do the dirty work for Triple H while he steals all the glory. It may not be the smoothest way to go about things from a storyline perspective, but I truly believe that the WWE desperately wants to have a Triple H vs. Shawn Michaels match at WrestleMania, and this would be a decent way to explain it—with Michaels becoming the heel.
Then, after Raw, both Triple H and Michaels could disappear from WWE programming for a while only to resurface down the line a couple times to remind people of their feud and ultimately begin the road toward a WrestleMania match.
As for Lesnar, the win will help legitimize him and set him up for success in the future. Whether he faces The Undertaker, The Rock or whomever at WrestleMania, Lesnar needs to look like a threat in order for the feud and match to be the best it can be.
Losing to Triple H would prevent that from happening, and since Lesnar has so much to gain by winning at SummerSlam, I'm confident that he will.
