From these rules it should have been a penalty.
When Rogan blocked Jones he was not eligible to do so. Because...
At the time of the block, the ball was still in the air (1. It had not touchced a UA (team B) player).
And at the time of the block, the ball was at the 38 yard line (2. Had not broken UA's (Team B's) restraining line which was the 40).
Also, at the time of the block it had not yet passed the 40 which was UA's restraining line and was still in the air(3. So it couldn't have touched anything passed the restraining line including the ground, a player, or an official)
Therefore, at the time Rogan blocked Julio, no UT (TEAM A) player was eligible to touch the free-kicked ball. And according to the rules, if they weren't yet eligible to touch the ball, they weren't yet eligible to block a UA player (Team B).
Video of the play Around 7:00 minutes in
If you pause it at around 7:06 you'll get this image, and if you watch it in motion you can tell what I have circled is the ball, and it has been descending and is just now about to touch players.
Sorry the pic is so big, imageshack is not cooperating.
