Elway's first two years, he wasn't John Elway.
He only had two games where he threw for over 300 yards and had 4 games where he threw for under 100 yards and 14 games where he threw for under 150 yards.
He never had a high TD to INT ratio until his 11th year in the league, an entire decade before the light turned on. Before that he had 160 TDs to 157 Interceptions.
The point is that John Elway wasn't the

John Elway that everyone thinks early in his career.
He was a lot like Josh Allen his first three years and he was smaller and less accurate.
I am sure that NFL teams see his potential and think that they can develop him if they get enough time.
If he gets the right coaching and enough time he has Elway potential.
