When NFL teams drafted five quarterbacks in the first round of the 2021 draft, the clock started ticking on when those prospects would become starters. Despite what teams say before, during and immediately after the draft, the vast majority of first-round quarterbacks become their team's full-time starter at some point during their rookie season.
Since the league went to its slotted draft system in 2011, 32 quarterbacks have been drafted in the first round. Of those 32, 28 became their team's primary quarterback at some point during their rookie season by starting consecutive games.
