If he continues on his current trajectory the Drew Brees comparisons will start to pop up everywhere. As others have mentioned, his lack of measurables will probably ensure he is here for the next two years because the NFL is obsessed with guys fitting a certain mold.
At this point the sky is the limit for this kid. He has done an amazing job over his first 1.5 seasons at the helm, and everything sets up perfect for him to have another huge year next year. An experienced line in front of him with 6 guys that have all started and played significant minutes, a talented RB in the backfield in Mo and multiple weapons at WR. As long as the line gives him time he has shown elite level decision making and accuracy.
This offense should explode in 2020 as long as whoever ends up running it doesn't mess with things too much. All the pieces are in place for this unit to take another step with a ton of returning talent and experience. Can't wait to see how it all plays out.
