Yeah, you're right that was Gindorf (they had just shown Ellefson on the sideline before that) but I'm pretty sure Watson was going to try to throw that ball. Problem was the block that Gindorf released was on AA defensive end John Daka who ended up making the tackle. Didn't seem like a very well thought out strategy there because they either were hoping that Daka would lose his contain responsibility on the initial sweep or that Watson could shake him on the reverse. They also blitzed the corner from that side which further muddled things up.
