Can't agree with that at all. He was clearly open, Weddle was trailing by a large margin (by NFL standards) and the safety wasn't going to get there in time. You see that, you hit it 100% of the time. When you go through progressions, you stop when you get to the open guy. Witten was the first read, he was open, it was the right play. The only thing that is remotely questionable is the quality of the throw...and why more plays like that aren't called more often.
