4 stats that prove 49ers are in a class of their own after 4 weeks

Niner Noise argues that the San Francisco 49ers have established themselves as the NFL's premier team following an undefeated 4-0 start to the season. Despite injuries, San Francisco sits atop the NFC West behind historically efficient play on offense and total dominance on the scoreboard.

Writer Casey McAleer highlights four key metrics backing this claim, including a league-best 57.5% third-down conversion rate and zero sacks allowed behind quarterback Brock Purdy. Additionally, the 49ers boast an NFL-best plus-58 point differential while scoring on 52.6% of their offensive drives.
