After being erased by the pandemic last year, Canada's version of the Super Bowl returns from hiatus this weekend. Here are some things to know about the 108th Grey Cup game, which kicks off Sunday at 6 p.m. ET in Hamilton:

It's a rematch. But the tables have turned

It feels like a million years ago, but in 2019 the Winnipeg Blue Bombers snapped their 29-year championship drought by beating the Hamilton Tiger-Cats 33-12 in Calgary. Two years, a global health crisis and an entire lost CFL season later, the same teams are back playing for the title.

But things are different. Back in 2019, Hamilton was the 15-3 regular season juggernaut that had scored the most points in the league and given up the fewest. The Tiger-Cats were four-point favourites against a Winnipeg team that went 11-7 and had to win back-to-back road playoff games to get to the Grey Cup. Now, the defending champion Bombers are the toast of the CFL after going a league-best 11-3 in the shortened regular season while scoring more and surrendering less than anyone else. They're favoured by, you guessed it, four over a Ti-cats team that went a pedestrian 8-6 before defeating Montreal at home and upsetting Toronto on the road in the playoffs.

Our head says Winnipeg

It's a testament to the Bombers' quality that they could turn the ball over a nightmarish six times in the West Division final vs. Saskatchewan and still come out with a 21-17 win. Even accounting for this rare lapse, Winnipeg is averaging 25 points per game this year and giving up just 14.

Winnipeg's defence is frightening. In terms of points per game allowed in the regular season, the 2021 Bombers are the CFL's stingiest team in a half century. Anchoring the D is linebacker Adam Bighill, who's up for his third Most Outstanding Defensive Player award. Up front, pass rushers Jackson Jeffcoat and Willie Jefferson combined for 16 sacks in the regular season and another two in the West final, where they each forced a fumble. Rookie defensive back DeAundre Alford tied for second in the league with four interceptions. Good luck finding a weakness to attack.

Despite its struggles on Sunday, the Winnipeg offence is scary too. Zach Collaros threw an uncharacteristic three interceptions vs. the Riders — half his total from the entire regular season — but was the CFL's most efficient passer this year and led the league in touchdown throws. He's expected to win Most Outstanding Player when the CFL awards are announced Friday. Collaros has a great connection with Kenny Lawler, the only player to top 1,000 receiving yards this season — though Lawler was held to just three catches for 49 yards by Saskatchewan. Winnipeg can also shred you on the ground with star Canadian running back Andrew Harris — a three-time CFL rushing leader and the reigning Grey Cup MVP. He returned from a knee injury last week to run for 136 yards and a TD.

But our heart says Hamilton

The underdog is always at least somewhat lovable, and the Tiger-Cats bring some extra narrative cuddliness to the table. When Hamilton lost the Grey Cup game to Winnipeg in 2019, it inherited the humbling title of longest-suffering CFL town. It's not quite as bad as the Bombers' was, but the Ti-cats' championship drought has reached a deeply unpleasant 22 years.

The last time Hamilton won the Grey Cup, the world's biggest worry was Y2K. The MVP of that game, quarterback Danny McManus, is now 56 years old. The Most Valuable Canadian, receiver Mike Morreale, is also a quinquagenarian who now runs a pro basketball league. So, yeah, it's been a while. And how heart-warming would it be to see the Ti-cats finally capture the Grey Cup in their own stadium, in front of their own fans?

If that happens, Hamilton will likely have its defence to thank. Anchored by playmaking linebacker Simoni Lawrence (the East nominee for Most Outstanding Defensive Player) and a strong set of linemen, the Ti-cats' D forced five turnovers in the playoff win over Montreal. It also held CFL rushing champion William Stanback to just 29 yards on 12 carries after allowing a league-low 4.2 yards per tote in the regular season. These guys could be a tough nut for Harris to crack on Sunday.

A backup quarterback might be the X-factor
