From the stands, it was clear that the O-line was doing an excellent job in pass-blocking.  Had Ainge's up/down accuracy been there, the stat board would have been a lot different, and there never would have been overtime.  As it was, there was a lot of overthrows and a lot of underthrows.  Fortunately, most of the overs were toward the sidelines, so they didn't set up interceptions.  Unfortunately, most of the unders were in screen plays, so one of the best tools to slow down a pass rush went out the window.  I couldn't see the footwork, but I'm willing to bet he's right.  It certainly wasn't pressure causing the problems.

However, the "fewest sacks allowed" is also Ainge's responsibility.  He runs through his reads quickly (not too quickly; he just doesn't take all day), and if the passes aren't there, he's not afraid to throw it away and play again next down.  Even if the Spurrier pass rush was effective, they would have had difficulty in sacking Ainge.  This, of course, does not include that sack near the end, where the rush finally came through and surprised Ainge.

As far as the first point:
I just dearly hope that they've been slowly working in some things to "mix" into the coverage, and finally feel that those new elements are ready to use.  I don't mind mixing things into an effective unit, so long as those new things are also effective.  Besides, the Lafayette game might be the time to test some new things; we should (should) be able to win that one handily, even with a special teams gaffe or two.
