Four games in, and the San Francisco 49ers’ offensive line hasn’t given up a single sack. After taking down the Denver Broncos 24-14 in Week 4, they’ve officially joined an ultra-exclusive club, a kind of league-wide unicorn situation that’s barely been seen in over 60 years. Seriously, this doesn’t happen.
An O-Line Showing Out Like It’s 1963
This isn’t just a good start, folks, this is bonkers. The Associated Press reports that only four other teams since at least 1963 have managed to start a season like this: the 2005 Colts, the 1989 Dolphins, the 1984 Dolphins, and the 1975 Cardinals. Think about that for a second: nearly six decades of NFL football, and only a handful of teams have pulled this off. It’s a massive testament to their offensive line. We’re talking about Trent Williams at left tackle, Connor Colby at left guard, Jake Brendel at center, Dominick Puni at right guard, and Colton McKivitz at right tackle, all staying healthy and straight up dominating. They’ve faced off against some serious defenses too, including the Los Angeles Rams and those Denver Broncos, and still, nothing. Zip. Zero sacks.
Historically, teams that hit this mark have seen some real success. The 2005 Colts went 14-2, nabbed the AFC’s top seed, though they eventually lost in the divisional round. The 1984 Dolphins also went 14-2 and made it all the way to Super Bowl XIX. The 1975 Cardinals finished 11-3, won their division, and got bounced in the divisional round. The 1989 Dolphins are the outlier, finishing 8-8 and missing the playoffs entirely. So, while it’s not a guaranteed Super Bowl run, it definitely puts you in prime position.
Purdy’s MVP Push And The Unbeaten Streak
This level of offensive line play isn’t just about protecting the quarterback, it’s about unlocking everything else. Brock Purdy is absolutely thriving because of it, pushing hard for that MVP conversation. In Week 4 against the Broncos, he went 19-of-30 for 218 yards and threw two touchdowns, all with no interceptions. His 107.4 passer rating tells you everything you need to know: he’s comfortable, he’s clean, and he’s making plays.
The lack of sacks is a huge deal, no doubt, but let’s be real, the 49ers are probably even more pumped about their 4-0 start to the 2026 season. That kind of perfect record this early is a huge statement.
Now the big question looms: can this incredible streak actually continue? Every week, the pressure mounts, and every defensive coordinator out there is probably losing sleep trying to figure out how to finally get to Purdy. It’s going to be wild to watch how long they can keep this up, but right now, this offensive line is playing at a historic level, and that’s a dangerous thing for the rest of the league.
