This exercise would intuitively seem to be easier than one would think. The quarterback position has become the most important in the NFL and possibly all of sports. We all know who the best NFL quarterbacks are and we have an idea of the year the were drafted but which drafted classes were the best and who was the best in each draft class this past decade?
It would make sense that teams would do their research and follow up to ensure the especially valuable high draft picks are spent on quarterbacks. It would make even more sense if all that research and expense actually paid off.
But does it? Is the best quarterback always the first quarterback taken? The answer would be no and the best proof of that is Tom Brady. Did each draft class of the past decade uncover any gems? Not as many as one would think but that doesn't mean the best quarterback was the first quarterback taken. Almost just as important is how many of those top picks didn't pan out. That number is a lot higher than you would imagine.
Each year in the past decade is broken down by best quarterback drafted, the second quarterback drafted and the biggest bust. Some years were especially bad and only one has particularly stellar (so far).
Each year is ranked so this does not go in chronological order.
