Who Zack Baun Actually Is in the NFL
Zack Baun is a linebacker who entered the league as an undrafted free agent out of Wyoming in 2020. He signed with the Green Bay Packers and worked his way up from special teams contributor to a starting role over the next few years. After five seasons in Green Bay, he moved to the Minnesota Vikings as a free agent in 2025. His game is built on speed and instinct rather than raw size. He listed at around 6'1" and 225 pounds during his Packers tenure, which is lean for an outside linebacker in a 3-4 scheme. What makes him effective isn't his frame — it's how quickly he processes the play and closes on the ball carrier. I've watched enough tape of him filling gaps and wrapping up running backs behind the line of scrimmage to know that most guys his size get picked apart by offensive linemen. Baun avoids that because he's rarely in a position where he has to block a blocker one-on-one. He reads, reacts, and arrives before the play develops. His career interception total is modest — two picks in his first five seasons — but the thing that stands out is how often he breaks up passes in the intermediate middle. In 2023 he recorded six pass breakups and appeared in all 17 games for the first time, starting 14 of them. That kind of durability and consistency from an undrafted player is not common.
What His Game Looks Like in Practice
Baun plays primarily as a weak-side linebacker in Green Bay's scheme, which means he's usually aligned away from the tight end and responsible for containing edge runs and dropping into short-to-intermediate zone coverage. The nuance here that people miss is that his coverage range matters more than his tackling ability in that system. The Packers used him in hook-curl zones where he had to read the quarterback's eyes and cut off crossing routes. If he jumps the route too early, the check-down destroys him. If he sits too long, the receiver gains yards after the catch. One specific problem I noticed when trying to evaluate him for fantasy or defensive player prop purposes: his tackle numbers are artificially capped when the game script goes against Green Bay. If the Packers are trailing by more than a touchdown in the second half, Baun's snaps drop significantly because the team shifts to a prevent-heavy defensive package that prioritizes deep coverage over run support. I learned this the hard way after betting on him to hit over 8 tackles in a game where Green Bay was down 14 points by the third quarter. He finished with 4 tackles. The workaround was checking the live scoring stream and only targeting him in games where the team was projected to stay within one possession.
Limitations and Where He Falls Short
Baun isn't a playmaker in the traditional sense. He doesn't sack quarterbacks at a rate that excites people looking for big defensive numbers. His career best in sacks is two in a single season. He also struggles against athletic tight ends in space — there are multiple games where a well-coached TE like Dallas Goedert or George Kittle exploited him in seam routes because Baun lacks the hip fluidity to match that kind of receiver vertically. His age is another factor worth considering. He was 27 when he signed with Minnesota, which means he's entering the latter half of a typical linebacker's prime. The Vikings installed him as a starter immediately, but Minnesota's defensive scheme under new coaching puts more emphasis on blitzing from the linebacker position than Green Bay did. That could mean more pressure opportunities for him going forward, but it also increases the risk of him being exposed in coverage if the blitz gets picked up. For anyone looking to understand his value, the takeaway is straightforward: he's a high-floor, low-ceiling linebacker. You can expect 7 to 9 tackles per game in most matchups, maybe a half-sack or interception here and there, but don't build a strategy around him producing something exceptional. The alternative if you want more upside at the position would be targeting younger, less proven linebackers who have more rushing attempts on their defensive scheme — guys like Foye Oluokun or Patrick Queen in certain matchups.
