Is your question is "why is Sanchez still in the league if he's a backup/stop-gap" the answer is that he's a backup/stop-gap level QB.

If your question is "why aren't there more good QBs produced in the US," there are a variety of factors at play there, including but not limited to: advent of spread offenses, competition from other sports, specialization of HS athletes, etc.

Bless you for trying.
