1. The 49ers don't ask Brock Purdy to win games by himself
Trevor Lawrence was under scrutiny last year for sometimes looking for the big play when he could've easily settled for a checkdown. That aggressiveness often led to mistakes and the offense stalling. Then again, he might've played a bit safer if the Jaguars hadn't routinely asked him to put the team on his shoulders to win.
When Zay Jones missed time, Jacksonville was ill-prepared for his absence. His presence was needed and the offense suffered as a result. The Press Taylor wasn't able to adjust and the team's inadequate depth was exposed. Also, the offensive line couldn't protect Trevor Lawrence or open lanes in the running game. This led Lawrence to try to do too much at times. That's rarely the case with the San Francisco 49ers and Brock Purdy.
While Purdy is an important cog on the San Francisco offense, they don't solely depend on him to put points on the scoreboard. Sure, they'll want him to deliver in the clutch but he doesn't have to be perfect for them to win. He's got a supporting cast around him that can bail him out when he makes mistakes and make plays when he's in a funk.
More often than not, Trevor Lawrence had to have a near-perfect game if the Jacksonville Jaguars wanted to win. If he wasn't in the zone, their chances of losing increased considerably, especially in the second half of the season. Meanwhile, Purdy played badly at times, but either other players (Christian McCaffrey, Deebo Samuel, Brandon Ayiuk) stepped up or the defense showed up.
Either way, the 49ers had a core of players who could step up when things weren't going great for Purdy. The Jaguars need to do the same for Trevor Lawrence in 2024.
