Sure, you can blow a game to a lesser-division rival. You can do it twice. But when you also show you can’t even compete with the best team in the league due to mistake after mistake, that means you aren’t winning much in January.
The 2024 San Francisco 49ers have coughed up a game to the Los Angeles Rams and the Arizona Cardinals and got dominated by the Kansas City Chiefs. Tell me who they could beat in the postseason.
Sure, they could win the division, they could nab a wild card spot, and they probably will.
