Tom Brady and Matthew Stafford are very nearly opposites. Brady is a noodle-armed former sixth-round pick who has achieved unparalleled success. Stafford is a cannon-armed former first-overall pick who has continually flirted with busting outright. I won’t belabor this. They’re little alike, but Stafford like Brady may benefit immensely from moving to another team.
The confounding but not at all contradictory fact is quarterback is both the most important position in the NFL and the most dependent position in the NFL. A great left tackle is a great left tackle. It’s a matchup position and a position which fails or succeeds largely in isolation.
