What happened: Jackson has been adapting to more under-center work in a new offensive system during training camp.
Why it matters: His adjustment will be measured against existing postseason pressure. Regular-season results will determine whether the rebound forecast holds.
By the numbers: Jackson completed 11 of 12 passes (91.7%) midway through an Aug. 13 training-camp practice.
What to watch: Baltimore closes the preseason Aug. 28 before turning to the regular season.
