In years 4 and 5 - he had 65 td's and 20 interceptions. In Goff's year 4 and 5 (so far) he has 38 touchdowns and 24 interceptions - again year is not over yet.
Rogers in year 4 (first year as starter but 4th year in league) he had 58td's and 20 ints
Again - these are hall of famers.
What is Goff's ceiling? - game manager - a better Kirk Cousins or Jimmy G? Matt Ryan / Joe Flacco? Ryan had 61 td's and 26 ints in his year 4 and 5
Goff's good enough to win a lot of games, but I worry if he's the chosen one, so to speak.
