Come on... those were two flat out horrendous calls that led to the Broncos getting 15 points. Even you can admit it. and the NFL and its calls are MUCH different than the NBA, since they have the ability to review and overturn stuff.
Chargers did have chances, but if those calls were correct, then the Chargers likely would have ended up beating the broncos quite solidly, possibly even blowing them out.
Fact is, if this was the Colts or Chargers getting those calls against the Patriots, you would go ape yourself, probably a of a lot worse than any of these Chargers fans here are.
