Sione Vaki May Have Just Changed Detroits RB2 Battle

Sione Vaki's standout pass-blocking in Week 4 propels him into a crucial role as the Lions' key running back depth is tested.

Sione Vaki gave the Lions a much-needed lift in Week 4, and the biggest difference came in the one area that mattered most against the Jets: pass protection.

Jahmyr Gibbs still found the end zone three times against New York, but his afternoon also laid bare a weakness that isn’t going away anytime soon. As a blocker, he was a liability. On multiple snaps, he simply got out of the way of Jets pass rushers, a choice that made sense if the goal was avoiding a hit or protecting his body while carrying such a heavy workload for Detroit.

That opened the door for Vaki. The third-year running back stepped in and handled the dirty work, delivering key undercuts on Jets defenders to help keep Jared Goff upright. He also added a season-high 26 rushing yards on six carries, giving the Lions something steady behind Gibbs.

The contrast with his first two games of the season was obvious. Vaki looked like a different player, and it was exactly the kind of showing Detroit needs from him if the team wants to avoid digging further into its running back depth.

Coming into the year, Vaki’s role was anything but settled. He missed enough training camp and preseason work because of injuries that it was fair to wonder how the Lions would use him, especially with Jacob Saylors in the picture at RB2. But the Week 3 win over the Jets clarified why Detroit kept him in that spot.

The value starts with protection. Vaki has shown he can block, and his background as a safety still shows up in how he moves on offense.

He’s also settled in as a runner. In the first two weeks, he had happy feet with the ball and kept searching for a lane, often settling for one or two yards.

Against the Jets in Week 3, he was more decisive and more physical, using his strength to grind out 3-4 yard gains that helped keep drives alive.

Saylors may have carved out a bigger role as a returner, but Vaki looks like the player who can lock down RB2. With Isiah Pacheco likely out for the rest of the season, the job is there for Vaki to keep. If he keeps stacking performances like this one, it’s hard to see anyone taking it away.

Lions Just Reopened A Roster Spot With A Familiar Return

The Lions made a familiar practice-squad swap Tuesday, parting ways with cornerback Natrone Brooks and bringing back tight end Miles Kitselman. Kitselman is returning to Detroit after previously being waived with an injury settlement, a transaction that had temporarily taken him off the teams roster picture but left the door open for a reunion down the line.

Kitselmans return gives Detroit another look at a player the organization already knows, while the move also keeps the tight end room in motion after a series of roster adjustments at the position. The broader backdrop includes the injury settlement process, which can create an opening for a later return, and it comes amid other recent moves involving tight ends and defensive end Ahmed Hassanein.

Dan Campbell Just Made Derrick Moores Path To Playing Time Clear

Derrick Moore has spent the early part of his Lions career a step behind, a familiar place for a rookie defensive end trying to climb a crowded depth chart while also dealing with lost practice time because of injury. For a Detroit defense that is still sorting through adjustments, the development curve has been especially important, and head coach Dan Campbell made it clear Moores next step is all about getting more work and turning those reps into trust.

Campbell said Moore needs those chances to keep growing, and that the expectation inside the building is he will improve and push for more playing time as he gets comfortable. Campbell also noted he has been spending extra time in defensive meetings to help with the ongoing adjustments on that side of the ball, which only adds to the sense that Detroit is trying to steady the group while waiting for younger pieces like Moore to catch up.

Lions Suddenly Have A Tough Center Decision Before Division Games

Juice Scruggs has handled the center job well through the first three games, giving the Lions something they needed in the middle of the offensive line after moving him into the role. He has graded out strongly and looked comfortable enough that Detroit now has a real decision to make as the schedule turns tougher, with divisional games looming against the Packers and Vikings.

Dan Campbell said Cade Mays is making progress in his recovery, but a Week 4 return may still be a stretch, and the Lions may choose to wait until after the bye before bringing him back into the mix. That leaves Detroit weighing continuity against the possibility of getting Mays back in place at center, a choice that could shape how the line holds up in the games that matter most for the division race.
