I think zero confidence in the QB possition is different to zero confidence in the passing game....or O in general.
If you look at todays game, it starts with....
3rd & 5 completion...1st down
3rd & 4 completion...1st down
3rd & 13 completion...1st down
Next drive....
After 3 straight runs....
1st & 10 SACK(Penningtons fault)
Next drive....
2nd & 8 SACK(no time)
Next drive....
2nd & 11 incomplete
1st half over.
I think if the OL held up for longer, JP would have had more passing opportunities.
