By way, the O-line performed well for Dobbs so we can't say the lack of completions were their fault.
It is interesting that you say that. On another thread, I mentioned that Dobbs seemed hesitant and unsettled in the Mizzou game. Someone (sorry, forgot who) responded that Dobbs would've been fine if the Mizzou defense hadn't been all over him all game (which by necessity implicates our OLine's protection).
So I went back and studied the first half of the game yesterday. Spent about 4 hours, just on the first half, fast forwarding through our defense and just focusing on our O.
I took notes, but didn't keep them overnight ... so apologies if my memory is off on some points. But here's what I saw.
Dobbs
was hesitant, didn't seem nearly as confident as he had in the previous games -- not even as confident as he'd been against 'Bama, which was not only a harder opponent (#20 defense vs. Mizzou's #41 defense), but was Dobb's first game of the year.
Not counting the final drive of the half (which was just a couple of handoffs to Hurd to run the last minute off the clock), there were about 28 offensive plays. Dobbs was only sacked in two of them, and was only pressured in a few more. He was largely well-protected in the first half, but still looked tight. [oh, btw, the first sack was a coverage sack ... Dobbs held the ball too long looking for receivers, 6 or 7 seconds, should probably have thrown it away after going through his progression and finding nothing]
He did complete the majority of his pass plays, but they were almost all screens out to the flat, often to Hurd. I think he only attempted four or five passes down field, and only one was complete (6 yards to either Pig or Von).
He also made bad calls on a couple of option reads, one where he kept but should've given the ball to Hurd, and the other where he handed off to Hurd but should've kept it (amazingly, Hurd turned the latter into a five yard gain when he should've been tackled behind the line of scrimmage).
So after watching that first half again, I think you are largely right (and I was right in my initial impression). There were a few plays where the OLine let the D through quickly, but that's gonna happen from time to time against the better defenses in the conference.
p.s. Don't get me wrong, I like Josh, think he has tons of upside, and think he generally played very well last year. Mizzou (and Vandy) just weren't two of his better games.
p.p.s. I'll go back and study the 2nd half of the game today or tomorrow...it may be that the OLine completely failed Josh then, as others have said.
