The SAM Swap: Why Winnipeg's Griffin-for-Smith Change Is a Scheme Bet, Not a Downgrade
The SAM Swap: Reading the Griffin-for-Smith Downgrade
Winnipeg's official depth chart landed Thursday morning with exactly one change: Jaylen Smith to the one-game injured list with a hip injury, Michael Griffin II back into the starting lineup at strong-side linebacker, and Canadian linebacker Lane Novak promoted off the practice roster to absorb the vacated roster spot. On paper it reads as routine injury bookkeeping. On film it's a scheme decision with real consequences.
Smith, a 24-year-old Hamilton native taken in the second round of the 2025 CFL Draft out of North Texas, has made seven starts at SAM and produced 46 total tackles — 6.6 per game. Griffin, in his third season in Winnipeg, has nine starts at the same spot and 39 defensive tackles — 4.3 per game. That's a 2.2-tackle-per-game gap, which across an 18-game season is roughly 40 tackles of production walking off the field.
But raw tackle counts flatter this position. In Winnipeg's front, the strong-side linebacker is the apex defender. He sets the edge against the run on the strong side, takes on the tight end or H-back in the run game, carries the No. 2 receiver vertical in their pattern-match Cover 3 looks, and serves as the primary blitz-carry defender on the back side of their pressure packages. Smith's volume says he was around the ball a lot. It doesn't say he was in the right place.
Griffin's résumé — 51 career regular-season games, 139 defensive tackles, 31 special teams tackles, four sacks, four pass knockdowns, one forced fumble, one recovery split between Winnipeg and Calgary — is the profile of a player coaches trust to be assignment-sound. He has already started nine games at SAM this season, which tells you the Bombers have been rotating this spot all year. That isn't a depth problem. That's a matchup lever.
The injury detail matters more than the name. Smith did not practice all week and was listed as questionable on the final injury report before being moved to the one-game IL. A SAM who hasn't taken a rep in a communication-dependent, coverage-heavy role is a liability against motion and shifts. Griffin at least has the reps.
Novak's promotion is the tell. Ten regular-season games, four special teams tackles, a fifth-round pick out of Balgonie, Sask. — that's a core-teams body, not a defensive one. Winnipeg is protecting its coverage units, which have quietly been one of the more reliable parts of this 8-8 team.
Why Edmonton Has Winnipeg's Number: The Four-Fumble Autopsy
Two meetings, two losses, eight total points. Week 4 at Princess Auto Stadium: 23-18, and the Bombers fumbled four times in the first half. Week 12 at Commonwealth Stadium: 22-19, and they lost despite Brady Oliveira rushing for 118 yards.
Those are two completely different failure modes, and that's the concerning part. The Week 4 loss was a ball-security catastrophe — four first-half fumbles is roughly a month's worth of giveaways for a disciplined team, and the fact that Winnipeg still only lost by five tells you the defense bailed them out repeatedly. The Week 12 loss was the inverse: the run game functioned, the offense moved the ball, and it still wasn't enough.
Eighteen and nineteen points. In a league where the median winning score sits in the mid-20s, that's the number that matters. Winnipeg has scored 18 and 19 against Edmonton and lost both by a field goal and a safety's worth of margin. You don't need a complex explanation for 0-2. You need to look at the scoreboard.
Third Down and the Red Zone: Where the Offense Stalls
Winnipeg's offensive identity under Buck Pierce is built on 21 and 12 personnel, inside zone and duo concepts for Oliveira, and play-action shots layered off that run action. It's a physical, condensed-formation offense that wants to stay on schedule and win on second-and-short.
The problem is what happens when it doesn't. When the first-down run gets stuffed and the Bombers are in second-and-eight or longer, the play-action game loses its teeth. The safeties stop biting. The intermediate windows close. And Winnipeg's protection has not been good enough to hold up in obvious passing situations, which is why you see so many checkdowns and so few explosives on second-and-long.
The red zone is the same problem in miniature. A condensed field eliminates the vertical shot plays that make the run game dangerous. Inside the 20, you have to win with contested catches, tight-window throws, and quarterback-designed runs — and that's where this offense has been at its least efficient. Oliveira's 118 yards in Week 12 came largely between the 20s. That is the entire story of a 22-19 loss.
Watch the first-down call sheet Friday. If Pierce comes out throwing on early downs to loosen the box, that's an acknowledgment the run-first script hasn't worked against this opponent. If he doesn't, expect another game decided in the fourth quarter.
What a Win Actually Requires
Three things, in order of importance.
First, zero turnovers. Four fumbles in a half is an outlier, but the Bombers have now put the ball on the ground in both meetings. Against a team you've lost to twice by a combined eight points, the margin is entirely self-inflicted.
Second, Griffin has to tackle in space. Edmonton will test the new SAM immediately — quick game to the boundary, RPOs that put the apex defender in conflict, and motion that forces him to communicate through traffic. If Griffin is a step slow to the alley, the Elks will run the same concepts that produced 45 points across two games.
Third, touchdowns instead of field goals inside the 20. Winnipeg can officially clinch a playoff spot with a win. They've already proven they can move the ball on Edmonton. They have not proven they can finish.
