I still struggle with one piece of data reporting in the box scores.

Sacks Allowed.

I feel like more sacks should be pinned on the linemen, because I see games with 7-8 sacks for a defense, but only 2 are credited as sacks allowed by the o-line.

What is the logic on this?

We probably need to look closer at this. The code does assign a blocked by to give credit for a missed block when a sack occurs. But it could be this flag is getting cleared out too quickly and the game doesn't recognized who was responsible.
