yikes maybe he got hit on the first throw but that second one was terrible
On the 1st INT, his arm was obviously hit. That's why it was a lame duck. On the 2nd INT, it was a zone blitz where the DE dropped into coverage and made the pick. Dobbs didn't see him when he made the throw. This is an exotic blitz/coverage that fools even the most veteran NFL QBs sometimes. This was regular season NFL defense that the Giants used in the preseason to fool Dobbs.
Here's a guy who does a pretty good breakdown of what happened on that second INT:
All in all, once you watch the tape, Dobbs INTs looked worse than they really were. The first one was because his arm was hit. The second one was because of a cleverly designed zone blitz that fools even veteran NFL QBs during the regular season.
