I dont mind the physicality but I was extremely frustrated at the inconsistency of calls this season. To me if you are a ref and are letting this stuff slide, which was happening all season, and not just for Seattle, you are indirectly choosing sides in a game by giving whichever team is cheating the hardest the advantage. To me I think that creates a crappy end product.
In not sure what the solution is but it's maddening to watch a team like Seattle basically interfere on every play and then see the opposite the get called for a ticky tack PI call later in that same game. Frankly if you aren't gonna call one, don't call the other, and if you are gonna call one, call them all.
