In 2016, Minnesota Vikings quarterback Sam Bradford set an NFL record for completion percentage by converting 71.6% of his passes, but not all of the credit goes to the man throwing the football.
Not only does it take an accurate arm and patience to deliver the passes where they need to go, the quarterback needs to be aware of what his receivers are doing and where they will be next. And that is something the Vikings did well last season.
Both Stefon Diggs and Adam Thielen have been praised for their work in route running.
