When you talk about quarterbacks nowadays, the one word you hear get tossed around is "elite." You'll hear people say, "This guy's elite, and this guy isn't."
The word itself might end up being overrated because of the way people tend to overuse it. It's also still unknown how many QBs should be labeled as elite and what the actual criteria is.
Philip Rivers, the quarterback of the San Diego Chargers, has had his name tossed around in the category of elite quarterbacks in the NFL.
