Denver is basically just making Von rush the QB every play and locking up that side of the line.
Opposing teams are running away from him most of the game when they run, and Rivers is a heady QB who utilizes his dumpoff valves at the first sign of pressure.
Most of his stat lines this year are going to be low tackles, with 1 or 2 sacks, and a few more QB Hits. But he's basically neutralizing an entire side of the LOS for Denver. Trust me, they are completely ok with his stat line.
