Vikings Are Trying An Unusual Chaz Chambliss Experiment

Could the Vikings' strategic shift with linebacker Chaz Chambliss bolstering their fullback position signal a significant adjustment for their offense?

The Minnesota Vikings have one preseason game left before the regular season opener on September 13 against the Green Bay Packers, and there’s still plenty unsettled on this roster. The quarterback situation behind Kyler Murray is still a mystery. The defense has been ahead of the offense all camp, but Brian Flores’s group remains very thin in the secondary and very young up front.

Now there’s another wrinkle: outside linebacker Chaz Chambliss may be working his way toward the offensive side of the ball.

According to Emily Leiker of the Star Tribune, Chambliss took a snap at fullback during joint practices last week against the Baltimore Ravens. Since then, the move has advanced enough that he has changed his number from 57 to 40, which would make him eligible to play linebacker and fullback.

“Remember how we mentioned on Access Vikings last week that outside linebacker Chazz Chambliss took a rep at fullback during joint practices with the Ravens? Well, he switched to No. 40, which would indicate there’s some steam there. The NFL has limitations around which jersey numbers can be worn at certain positions, and Chambliss’ No. 57 is not among eligible numbers for running backs.”

Chambliss came to Minnesota as an undrafted free agent last offseason and played in 12 games as a rookie. Most of his work came on special teams, where he logged 183 snaps, but he also saw 25 snaps on defense. His first NFL season ended with 8 tackles, 1 TFL and 1 sack.

The bigger picture, though, may be less about a full-time position switch and more about how the Vikings are building around rookie fullback Max Bredeson. Minnesota has spent camp talking up Bredeson’s impact on the run game and beyond, and that kind of role requires a backup plan.

So while Chambliss may not be headed for a permanent move to fullback, he could give the Vikings an emergency option there if Bredeson is ever unavailable. For now, that looks like the most likely explanation for the switch.

Vikings Have 3 Players Running Out Of Chances Fast

The Vikings second preseason game did more to sharpen the picture than soften it, and not in the way the coaching staff would have preferred. Against Baltimore, Minnesota got another look at a few players fighting to stick, and the returns were uneven enough to raise real questions about how soon they can be trusted in regular-season roles.

Michael Jurgens had a rough night at center, Max Brosmer struggled at quarterback and threw an interception, and first-round pick Caleb Banks still has not shown he is ready to help right away. There is still time left in the preseason for Minnesota to sort through the depth chart, but for these three, the margin for error is starting to shrink. [Read more 🡒]

Vikings Suddenly Have A Bigger J.J. McCarthy Problem Than Expected

The Vikings preseason has already raised more than a few questions, and J.J. McCarthy has been at the center of them. After what was supposed to be a key stretch for the young quarterbacks development, the early returns have prompted some concern about whether he has taken the kind of step Minnesota wanted to see, especially with the final preseason game arriving before the August 30 roster cut-down deadline.

There is plenty else hanging over the roster, too, from a thin edge rusher group behind Dallas Turner and Andrew Van Ginkel to the reality that veteran help at that spot is not exactly sitting around in free agency. Brian Flores ongoing discrimination lawsuit also remains part of the backdrop as the team moves toward its final exhibition game, but the bigger issue for the Vikings may be whether McCarthys preseason has left them with more uncertainty at quarterback than they expected.

Vikings Roster Crunch Could Turn Unexpected Bubble Names Into Trade Chips

The Vikings are heading into the roster cut deadline with more decisions than usual, and that has turned a few familiar bubble names into possible trade discussion points. Zavier Scott has flashed enough in camp and preseason work to get attention as a depth back, while Jeshaun Jones has drawn interest as a receiver with upside, and J.J. McCarthy remains the most notable name of the three simply because of where he stands in Minnesotas quarterback picture.

With the team needing to get to 53 players, any trade talk around that group is less about blockbuster moves than about value management. A player who might not make the final roster could still have enough recent performance, contract control, or positional appeal to bring something back before the Vikings have to make the hard call, and that is what makes this deadline worth watching from Minnesotas side.
