Brock Purdy just keeps making history, folks. After the San Francisco 49ers’ 24-14 win over the Denver Broncos in Week 4, Purdy is now the only quarterback in NFL history to start 4-0 with one or fewer sacks, fumbles, or interceptions combined. Seriously, let that sink in. The dude is playing clean football like we haven’t seen before, and he’s locked in that No. 1 spot in the QB power rankings heading into Week 5.
Purdy’s Numbers Are Absolutely Bonkers
This isn’t just about winning games, it’s about how he’s winning them. Purdy is leading the entire NFL in passer rating at an insane 126.2. He’s also top of the league in passing success rate (61.9%) and expected points added (EPA) per dropback (0.53). We’re talking about a level of efficiency that’s almost unheard of. His 0.53 EPA per dropback is the second-highest through four games in the 21st century, right behind Tom Brady’s legendary 0.59 in 2007. The kid is co-leading the league with 11 passing touchdowns already, and he’s ranking fifth in completion percentage at 69.9%. These aren’t just good numbers, they’re historic. He’s not just holding onto No. 1; he’s earning it every single snap.
Mahomes and Jackson Are Still Balling, But Can’t Catch Up
Even with Purdy setting the world on fire, the league’s other elite QBs are still putting on clinics. Patrick Mahomes has the Kansas City Chiefs out to a 4-0 start himself, and when he throws outside the pocket, nobody is better. He’s leading the league in both completions (23) and passing touchdowns (five, tied with Aaron Rodgers) from outside the pocket. Mahomes is top 10 in pretty much every key passing metric you can think of. If it wasn’t for Purdy’s all-time start to 2026, Mahomes would absolutely be back in that top spot. He was previously not No. 1 due to a torn ACL, but he’s clearly back in form. Then you’ve got Lamar Jackson, who keeps showing us why he’s one of the most efficient players in the game. In the Baltimore Ravens’ 24-18 win over the Tennessee Titans, Jackson completed 15 of 20 throws for 222 yards and two touchdowns, plus he chipped in 20 rushing yards. He’s second in the league in passer rating (119.6) and second in EPA per dropback. These guys are playing at an elite level, but Purdy’s just on another planet right now.
Heading into Week 5, the big question is whether Purdy can maintain this historic pace. With Mahomes and Jackson hot on his heels, the battle for the top of these QB rankings is going to be wild. Every snap matters, every stat counts. Who steps up next? We’ll be watching to see if anyone can even come close to what Purdy is doing right now.
