The San Francisco 49ers made it through their "dress rehearsal" preseason game, and we did indeed see the starters get a lot of work. The starters played the entire first half, with some of them getting additional work into the third quarter. This meant players on the back-end of the roster fighting for roster spots were the ones taking the biggest hit on snaps. This game might give us some indications on roster cuts. There could be different explanations for different low snap counts, but it gives us a starting point. You can view the gamebook here.
