On the Iowa State thing - it's been shown here to clearly be good. However, I will admit if you just saw what they showed on TV or heard Eli Gold (as did I that night), it's understandable.
Here's something to remember: my good friend Tom Ritter, the former official, told me that TV shows you things incorrectly. I made up the part about Tom, but that's true.
Some of y'all might remember the infamous Fog Bowl game in the playoffs between Philly and Chicago on the last day of 1988, when a fog rolled in off Lake Michigan and the TV viewers absolutely could not see the game at all. If you're watching it on TV IT LOOKS LIKE the players cannot see each other at all - but this is an illusion. The rule the officials opted to observe was that they could clearly see - down on the field - from end zone to end zone at all times and as long as they could, the players could do so the game continued.
In theory, that does away with the PASS, right, because you can't throw any deep balls. But Randall Cunningham threw for over 400 yards in that game - an insanely high total in a playoff game in 1988. I repeat - Randall Cunningham, the RPO quarterback who was basically a better Mike Vick and whose threat at that time before blowing out his knee was with his legs.
My point is that I'm willing to say that TV camera angles on things like field goals can sometimes look a little misleading. I, too, honestly thought we got away with one, but someone posted a different angle here at one time, and it settled the case for me with a straight-on shot. An announcer watching a monitor or a fan watching TV, it's understandable why it was like 'whoa, we got away with it." But we didn't.
