Haushka had a 49 yarder blocked in the previous game against Arizona. When he lined up for these three kicks, they were all similar range in a situation where a blocked kick was extremely undesirable. When these attempts were happening It felt like a blocked kick for a TD would allow Arizona to steal the game.
You could easily tell that Haushka was trying to get air under the kicks to avoid blocks. That messed with his accuracy just barely enough, all three of those kicks would have made it from 40 yards, and one of the kicks very nearly fell short.
