I think it was a cheap shot.
This is the best view I've found so far. If you watch on the video in this article attached to the "Fansportsclips" Twitter, it shows he had no one to block when the ball was thrown, and you'd think Boutte knew the ball was being thrown at about the 5 second mark. It sure looks like he turned his head to the right when the ball was thrown, but the video of him gets blurry and he moves out of the camera view. By the 7 second point of the video, the interception has occurred.
After the interception has occurred, the sideline official is waiving his arms, but it is so loud, I can't hear a whistle. By the 8 second point the defender is up and running. By the 9 second mark, Boutte is back in the camera view, and the hit happens at the 10 second mark.
I'm sure both schools have their own wide angle camera view, and if it is clear that Boutte was looking in the direction of the defender when that interception was made, then you've pretty well taken away any doubt. If that is what it shows, I think this rises to the level of warranting the most severe game suspension punishment maybe ever for a "flagrant" hit.
There are cheap shots, and then there are things that are a whole different category. That's why I said what I said. But I do believe you be thorough. I thought it was a cheap shot before, but relying on just the replay video wasn't in my opinion conclusive enough to make that determination. A wider angle camera view, if it shows what I think it will show, would be the final nail in the coffin, and enough to throw the BS flag on his claim of not knowing.
