Quarterback in the National Football League is the most important position in sports. Arguing otherwise seems foolish.
You’d think teams wouldn’t hold back when it comes to using resources to have the best quarterbacks possible, but that’s not the case. It’s rare for a team to use significant capital to acquire two quarterbacks at the same time hoping one works out. When the Chicago Bears signed Mike Glennon and drafted Mitchell Trubisky second overall in the same offseason, they were laughed at (it didn’t work, but that’s because they picked the wrong players, not because they doubled up).
