Have you looked up how many times has Haener been sacked? The answer is 6. How many quarters of football has Haener played vs Rattler? The answer is ~4 vs 14. How many times was Haener sacked last game vs how many times Rattler was sacked last game? The answer is 3 vs 0.
Stats are great, but stats don't tell you that Rattler is a rookie who started the season as the #3 QB. I'd expect an 11 year veteran starter like Carr to not take as many sacks as a rookie 3rd string QB who was shoved into action at just about the lowest point the Saints were as a team.
