But as you noted in one of your earlier posts, Palmer was chucking the ball downfield more than Murray.
Palmer's 7.6 yards per attempt (with Arizona) resulted from a 62.5% completion rate at 12.2 yards per completion.
Warner's 7.5 yards per attempt (with Arizona) resulted from a 65.1% completion rate at 11.6 yards per completion.
Murray's 7.0 yards per attempt resulted from a 67.1% completion rate at only 10.5 yards per completion. It's easy to have a higher completion percentage when you're a checkdown Charlie.
BTW, in his first three years Murray was a bit better, with 7.3 yards per attempt, resulting from a barely lower 66.9% completion rate at 10.9 yards per completion. But in his last three years, Murray has only managed 6.7 yards per attempt, resulting from a 67.3% completion rate at only 9.9 yards per completion. In 2024, Murray ranked #26 of 36 qualifiers with only 10.4 yards per completion.
