Dont know whats happening in the 2nd.
Maybe feels pressure seeing the other QB play (which hasnt been the case until recently)?
He's seeing the defense not being able to stop anyone and needing the offense to put up 7 points every drive. He's trying to make shyt happen and he's does not have THAT kind of level right now to do it consistently. So for every risky shyt that works (passes to Kittle and CMC on our last TD drive) there's gonna be a lot more than don't work (three INTs). He was also running a lot today trying to move the chains.
Basically he's trying to play like a top QB whose teams fully depends on his play, and when he's down 1-2 scores in the second half, he's been pressing and forcing shyt to close the gap. And that's not how we should be trying to do shyt on offense. Kyle has been giving him waaay too much responsibility for a player that still has a lot to improve upon, while at the same time having the playmakers to play more complimentary and balanced football. It's just a dumb and failed gamble by our HC.
Like @ysef said, we've become a finesse team that requires everything to work like a perfect clock. When shyt gets going we look dope, but as soon as there's some issues (injuries, penalties or just a bad day from someone) we look lost as fukk. We don't have any backup plan on offense and it seems our QB realizes that and is trying to fix shyt by himself. And that's gonna be a losing formula more times than not.
