The Arizona Cardinals had 14 points on the board really fast on Sunday. Justin Bethel and then Tyrann Mathieu both intercepted passes and returned them for touchdowns. If you look at both plays, they look an awful lot alike.
Take a look.
Here is Bethel's interception:
Now have a look at Mathieu's pick:
They look almost exactly the same.
They were a little different, though. The throw Bethel intercepted was father down the field. Kaepernick was trying to get the ball to the first down marker. He was under a little pressure from Frostee Rucker, but it appears what affected the throw was Rucker's jumping to try and bat the ball down. Kaepernick perhaps didn't step completely int to the throw, as it was a little wobbly.
Mathieu's pick came when Kaepernick was under heavy pressure. He was just trying to get rid of the ball, but still tried to get it to Anquan Boldin, who was only five yards past the line of scrimmage.. He threw it off his back foot, so there was no zip on the throw. It was just a poor decision and Mathieu saw it coming.
This SB Nation post called the plays nearly identical. The way the two players made the play looked the same, but the circumstances and the throws were different.
