Derek Carr got his 1st career win while having a passer rating under 70 in a game. He had previously been 0-25 in such games.
His 65.5% passer rating in Monday nights game against the Panthers is the worst passer rating he has had in his career while getting a Win.
If you can get a win while posting a sub 70 passer rating I'd say things can only get better. It speaks volumes to the overall team play including the defense playing at a very high level. After a mediocre overall performance in week 2 Carr is still at or near the top in several QB statistics. The one that counts the most is winning. Everyone should be happy about a 2-0 start, no matter what it looks like.
