Why was AA in on the last two series

This is driving me crazy. At some point Cole Kelly needs some reps.
As sad as our OL is, AA could possibly go down soon.

:?

On one hand, I certainly agree leaving AA in AFTER a game is “well in hand” may very well get him injured.

On the other hand, we are now without 83% of our offensive production from last season. I can understand why the coaches may feel the need to have the Ones get as many live-game reps as possible now … to set up a solid last-half of the season.

And there IS this: At least Cole Kelley is getting SOME reps via the Steamboat; in other similar situations, the back-up QB may not see the field at all.
