He was a 63.8% passer for the year. Here's each FBS game in time order with completion percentage:

BYU- 75.0%
SJSU- 69.8%
Arizona- 88.9% (but this isn't a great example, because he was hurt after 9 passes)
ASU- 54.3%
Oregon- 58.1%
UCLA- 68.2%
WSU- 53.8%
UW- 70.4%
WVU- 46.2%

So plotting that, it's not exactly a regression. Two of his 4 best games are late (UCLA was 11/3 and UW was 11/18).

Same with yards. He's over 275 against UW, WSU, and Oregon (all later) but below 200 against ASU.

Ratings are similar too:

BYU- 145
SJSU- 162.4
Arizona- 217
ASU- 68.6
Oregon- 130.7
UCLA- 217.5
WSU- 112.6
UW- 178.6
WVU- 99.5%
