49ers grades vs. Cardinals: The offensive line is officially a strength

Key Points:

• The San Francisco 49ers secured a playoff spot with strong performances across most positions, highlighted by quarterback Brock Purdy's efficient and effective play, earning him an A grade despite a 55.6% completion rate.
• Running back Christian McCaffrey also received an A for his impactful rushing and receiving, including forcing missed tackles and maintaining possession late in the game, while the wide receiver group was rated C+ due to limited production and reliance on Mike Evans, who may be sidelined.
• The offensive line was a key strength with an A- grade, showing solid pass protection and run blocking, despite minor injuries, while the tight ends earned a B+ for combining blocking and receiving contributions.
• Defensively, the line and linebackers struggled with depth and consistency, earning B- and C+ grades respectively, with notable effort from players like Dre Greenlaw and Fred Warner but overall diminished effectiveness.
• Special teams were a weak point with a D+ grade due to critical errors and missed opportunities, and coaching received a B for effective game management and trust in key players, though defensive coverage and pressure tactics showed room for improvement.
