Brock Purdy has been the story over the last six weeks of the 49ers season. Since stepping in when Jimmy Garoppolo went down with an injury the rookie has put up numbers that rival those of Joe Montana and Steve Young.
In the season finale against Arizona, Purdy completed 15 of 20 pass attempts for 178 yards, and three touchdowns. Purdy became the only quarterback since 1950 to win his first five NFL starts and throw two or more touchdown passes in each game. His three touchdowns also gave him 13 for the season, a franchise record for a rookie.
Here is every drop back for Purdy against the Cardinals.
Kyle Shanahan uses his personnel to create an open throw for Purdy. Kyle Juszczyk lines up as a win on the left. Deebo Samuel motions from out wide into the backfield and Christian McCaffrey motions to become a wing on the right.
At the snap, Samuel and McCaffrey run outs drawing Cardinals defenders with them. This leaves no defender in the middle of the field and Purdy hits an uncovered Juszczyk for a gain of 26.

Motion from Elijah Mitchell moves the Cardinals defense leaving George Kittle alone. Purdy sees it and hits the tight end for a gain of nine.
Purdy works to his right. Deebo Samuel is covered, leading him to Jauan Jennigs. When he starts to throw the defensive end is in the throwing lane, he gathers and throws side arm to Jennings to get it around the rusher. The pass is slightly off the mark and Jennings is unable to bring it in.
Facing third and 18, Purdy works to his left. As he starts to throw to George Kittle, he notices the corner is in position to make a play on the ball. Purdy brings the ball down and escapes to his left. He tries to fit a pass in to the tight end along the sideline, but it falls incomplete.

Purdy throws a screen out to his right to Elijah Mitchell. Mitchell catches the backwards pass, turns the corner, and runs for a gain of 37. He would score from six yards out on the next play.
