At Pro Football Focus, every player, on every play, of every game is tracked and in doing so, we chart every conceivable data point available. With 10 weeks of data from the 2017 NFL season to filter, PFF's Brian Spoon takes a look at how often quarterbacks use 3-step concept dropbacks, and how well they perform when they do.

Below is a list of the 29 quarterbacks who qualified (by attempting least 15 pass attempts on 3-step concepts), all ranked by passer rating on such throws. The top-2 of the list may not surprise you with how well their respective teams have fared this season:

*Note: these numbers do include those 3-step concept passes on designed screen plays.

Passer rating on 3-step concepts: 130.2

Goff is having a breakout season in his second year, and his performance on 3-step concepts is no exception, as he sees the highest passer rating on these passes. Under new head coach Sean McVay's scheme, Goff has attempted 42 passes on 3-step concepts, completing 31 of them for 351 yards with four touchdowns against no interceptions. He has an average depth-of-target of 3.0 yards and has been pressured on only five of these dropbacks (11.6 percent), a rate good for eighth-lowest among qualifying quarterbacks.

Passer rating on 3-step concepts: 118.5

Wentz is our sixth-highest graded quarterback (85.0 overall grade) through 10 weeks, and his use of 3-step concepts is a big reason why. With head coach Doug Pederson helping his young QB with open, quick reads, Wentz has the most pass attempts (103), completions (73), yards (698), and touchdowns (nine) on 3-step concepts. These dropbacks comprise 35.4 percent of his total, the highest rate in the league.

Winston leads the NFL in average depth-of-target on 3-step concepts at 8.4 yards (average is 4.7). This isn’t surprising considering he also leads the league in percentage of total passing yards coming through the air (68.3 percent).

Passer rating on 3-step concepts: 104.2

His average depth-of-target (7.9 yards) is third-highest among qualifying quarterbacks.

Passer rating on 3-step concepts: 97.0

McCown has taken 3-step concepts 21.5 percent of the time, ninth-highest in the league. He has completed 42-of-62 passes, throwing three touchdowns and no interceptions. Though McCown has been sacked 32 total times this year (second-most in the NFL), only one of those has come on a 3-step drop.

Though he has been incredibly accurate at this range (a league-best 91.2 completion percentage), he has used 3-step concepts just 11.3 percent of the time, the fourth-lowest rate in the league.
