Our defense has room to grow in specific areas and situations and probably wasn't the #2 defense in the league, but no this defense wasn't average and no the defense wasn't blowing the leads. By all accounts, our defense was better with the lead than trailing. With the lead, QBs had an 86.6 rating against us. Trailing, QBs had a 106.2 rating against us. This would suggest the complete opposite of what people suggest.
I think it's obvious that our offense was by far the problem last season and you have to go through so much mental gymnastics to blame our defense for the stat this thread is based on. The offense was 29th in turnovers and were by far worst in the league on offense outside of the first quarter. Meanwhile our defense was given statistically the worst starting position in the league, had the 3rd best average drive time, 1st in average amount of plays per drive, 2nd in average yards per drive, and 15th in average points per drive.
I wonder if the turnovers and average starting position played a part in points allowed lol... Totally the fault of the defense!
