Does make sense, Red. When we played them last in Seattle, Chancellor and Sherman were grabbing, PUNCHING and doing all sorts of crap with NOTHING getting called. Yes, we had several games where we were doing our share (Niners game and Chicago game), but that was mild compared to the mugging Jones and Nelson got in that game.
The PI calls are still the most mistakenly called. Hasn't changed much since the days of Michael "velcro hands" Irvin and his constant push offs on DBs. He could've been called on every play, but the refs almost never called it.
