And Tyrod was taken in the 6th round. Russell Wilson in the third. Brady in the 6th. 1st round QB's mean nothing anymore because teams don't have to commit huge financial resources. EJ was thought to have the highest upside in his draft year by multiple teams and scouts including the Bills. What the Cowboys thought back in the day, who also had a 4th round grade on Kiko Alonso, is irrelevant now.
And it works both ways. If EJ can't beat Tyrod then he shouldn't start, let the best man win.
