There are plenty of ways to define consistency at the quarterback position. Perhaps you see consistency as a quarterback playing at the same level game in and game out. Maybe consistency, to you, links to longevity -- a quarterback who can play at the same level for a long time would be considered reliable.

There's no single way to define the term in football, but we've got a pretty interesting statistic here at numberFire called Success Rate that can at least give us an idea of quarterback consistency.

Essentially, Success Rate takes our Pro Football Focus, among relevant passers last season, he ranked closer to the bottom in 20-plus yard attempts -- the lack of big plays probably hurt his efficiency a bit.

Lastly, there's Mark Sanchez. We can't understate his well above average Passing NEP per drop back in Chip Kelly's system last year, and that he was successful on nearly 50 percent of his passes. Whether he could keep that up over an entire season is a question mark, and considering his failures in New York, this should only be good news for Sam Bradford.
