The road to WrestleMania is in full swing, and the main event for the biggest show of the year has almost taken shape.

It was revealed on RAW this week that the No. 1 contender for Triple H's WWE World Heavyweight Championship at WrestleMania 32 will be determined at Fastlane. Brock Lesnar, Dean Ambrose and Roman Reigns will all go head-to-head in a Triple Threat Match at the Feb. 21 event.

The winner of that bout will go on to battle "The Game" at the "Show of Shows" on April 3 at AT&T Stadium in Texas.

Here is a ranking of Triple H's possible opponents based on all the circumstances leading into the event.

3) Brock Lesnar

"The Beast" is currently the WWE's biggest draw, but he's the least intriguing option to clash with Triple H at WrestleMania. The WWE has done this match several times before, and the two even collided at WrestleMania XXIX three years ago.

Instead of recycling a past match, the WWE's greatest event could use a fresh name on the marquee. Lesnar is involved with The Wyatt Family and should face Bray Wyatt at WrestleMania.

2) Roman Reigns

Reigns probably makes the most sense from a booking standpoint considering Triple H has done everything in his power to keep the belt off of him, but it doesn't make him the most intriguing option. The Leader of the Roman Empire has improved drastically in the ring, but he may not be deserving of a main event slot at a second straight WrestleMania.

From the creative side, the WWE obviously wants Reigns to come in as a babyface and take on the evil Triple H, but the fans may not view it that way, meaning the whole storyline could backfire on the WWE like it has in the past. A jam-packed AT&T Stadium can be boisterous if it turns on Reigns. The Undertaker needs an opponent and perhaps Reigns can fill that void.

1) Dean Ambrose

The WWE hasn't shown much faith in making the "Lunatic Fringe" into a top draw, but the fact that he's been able to hang around the main event scene as a tag partner to Reigns shows that he has what it takes to come up with great performances. Ambrose is somewhat of an anomaly because he's one of the guys that the WWE wants to be a fan-favorite, and both "smarks" and "marks" alike seem to be into him.

That's why he's the most logical Superstar to put in the main event. The WWE Universe would go nuts cheering on Ambrose to unseat Triple H as champion in an unexpected main event at WrestleMania. It's probably the least likely scenario, but Ambrose vs. Triple H is a fresh mathcup and is best for business.
