As I saw it, and I've looked at the replay a number of times, a penalty
could have been called on both plays...and on many occasions in many games would have been. (The first was actually more of a hold, by the way. Our DB appeared to grab the receiver's jersey.)
As we know, however, officiating is not scientific or perfectly consistent. These are bang-bang judgment calls. Also, defensive backs get away with a lot more contact these days than was once the case. The game is a lot more physical in the defensive backfield.
To be clear, I was overjoyed that neither call was made and don't feel the slightest bit guilty if we got a bit of break from the zebras for a change. I'd have been even happier if we got the same type break against Michigan or Ohio State, but figure the odds.
As for the TV commentary, both Danielson and Nessler agreed that the USC receivers were interfered with, but I don't think they overdid it. I mean, there were obviously a couple replays shown, and it's their job to comment on what they're seeing. I think they would have said the same thing if the teams had been reversed.
I know one thing: if the teams had been reversed, I'd be screaming bloody blue murder.
If you're interested, go to the 2:14:00 mark of this game replay to watch both plays in question:
