He played terribly last night but given the situation it's not all that surprising. Josh said something after the game, I assume he was talking about Jim Mora but not sure but he said in college one of my coaches told me "don't turn a traffic accident into a fatality", what he meant was that last INT and the fumbles he was trying so hard to make plays, he forgot about ball protection and it cost them. That was the thing that drove me nuts about Jake for his 6 years here, he never learned the value of protecting the ball, that sometimes it's better to throw it away or cover up and take a sack and punt, instead of throwing it up for grabs. Josh is a smart kid, he had some rough patches at UCLA as well, I'm hoping what he said last night is what he learned last night.
When 3/5ths of your OL is backups and interior guys, there's no predictable pocket to step up into, when their outside guys beat their man what do you do, that's where Josh not being more mobile is an issue. But I said it before and say it again, a mobile QB in this offense and this OL is a recipe for disaster because he'll be running all the time and getting hit and eventually get hurt.
We're lucky Josh didn't get hurt last night he took a hard fall on his shoulder, the last toe injury, and a couple of other really tough hits.
