ENGLEWOOD, Colo. -- Brock Osweiler, to his credit, understands his situation.
He is a quarterback who will make his fourth career start Sunday against Oakland. In the lengthy history of the NFL, no quarterback who ever became a long-term success did not step into the starting role as a finished product.
Even the best had hiccups. In 1983, John Elway got removed from the lineup, re-inserted, and removed again. That same year, Dan Marino had the gold standard of rookie seasons, and in his sixth career start, had a clunker at New England, completing just 14 of 37 passes and finishing with a 38.
