Yeah I don't really have a problem with spitting being a three-game suspension, and I don't even really care that Stammer got off the hook completely--because as we know, the league is all over the f***ing map on what is and isn't punishable.
The part that I don't like is we routinely see intentional physical acts that are far more dangerous go unpunished, or receive minimal punishment. Let's have some proportionality for these things; if we're okay with spitting being three games (and again, I am) then dangerous hits/checks/slashes/etc. should be getting five games, minimum.
