I guess you weren't watching. Stephen Jones was literally throwing phones.
FWIW, there was a tweet that I can't remember where I saw it that the one reason the Cowboys were upset was they thought they had a deal in place with the Bears for them to move up to 34 and it fell apart. So Dallas then just took Smith at 34.
Waste of a pick
Not sure what that's got to do with your interpretation. They could have been frustrated that Ogbah was taken. It doesn't equate to panic.
Like I said, with two picks ahead of them in the round, the chances they didn't see this scenario coming is exactly zero.
