Bizarre ending should actually have been touchback, right?

[Canned Heat]

Maybe I'm seeing things, but if you pause it at the :19 mark, it looks as if he catches the scrimmage kick attempt at about the 2 or 3 yard line (I think I see goal line and 5 yard line on each side of the players...look at pylons, too) and advances to the 12 and then spikes it backwards...where it is picked up and returned for TD. Looks like a good call and score to me.

As for how we would handle that....In 5 man we would obviously have 2 men back under the posts for the FG attempt. When it was certain to be short by the BJ (or LJ) he would run up from the posts and make sure the ball did or did not cross the goal line (becoming dead) and either kill it or bag the spot and point the other way towards us so we knew we had a live ball situation. In 4 man (JV/FR) we would have LJ back and white hat catching the other post. LJ would run up to rule on ball crossing the GL and becoming dead or still live..as is what happened here. Good goal line reaction by BJ & LJ from the posts.

Also...is that an inadvertant whistle I hear right before the score..?
