The above chart highlights the quarterbacks and where they were taken. A green highlight denotes that the quarterback finished in the top five. A yellow means they exceeded their draft position and finished in the top ten. A red highlight means that they weren't worth the pick where taken, finishing below their draft status, or not being much of a factor.
Of the six playoff teams that had top five quarterbacks, only two were drafted in the first two rounds (Manning & Brees). The others, Stafford, Rivers, and Dalton were all drafted in the sixth round or later, and after the 14th round in Rivers and Dalton's case. Adding to that we see Tony Romo, Luck, Big Ben, Wilson, Newton, all finished in the top ten, with Romo leading Bomba to the finals. Granted, Aaron Rodgers will more often than not always finish in the top five, so Sev.i did get screwed there, but injuries or not, this is about whether the pick was worth it. Obviously, last season, Rodgers didn't warrant a 2nd round pick.
Conversely, looking at the chart, notice how many teams missed on quarterbacks. These picks could have been used on other positions and garnished a much better return on investment. Had a team like Jaj not reached on Kapernick and waited a few rounds, he could have bolstered his team up significantly. Prime Time whiffed on his draft strategy of taking two Qbs and trading one, but lucky for him, one of those Qbs was Peyton Manning. What is interesting to note is that Hangin' and Bangin' had two duds for their Qb, yet still made the playoffs. For the most part, teams that gambled at the QB position early in the draft and missed (Sev.i, Jaj) were hurt a lot worse than teams that missed at the QB position later in the draft (Hangin', Hartan). If you go QB early, it has to be a winner, or else your season can sink fast.
HBK nailed his QBs, selecting two top five quarterbacks. He immediately gave himself a leg up on the league and had a bargaining chip at his disposal. Three non-playoff teams did well too, Awesomeness, BDiddy, and Vosgee, getting great value for the Qbs they took in the mid-rounds. BDiddy especially nailed it with Dalton in the late rounds. Since they didn't make the playoffs, it could be assumed that either these teams managed their draft poorly, or they faltered at other positions. In BDiddy's case, he ended up trading Dalton before the season even started, a move that I'm sure he would have loved to have back.
So what do gain from this? Well, we can note that yes, in order to make the playoffs, you need a top QB. The chart tells us that of the quarterbacks finishing in the top ten, eight were drafted rounds 4 or later, with three available in the fourteenth round and on. Yes you need a good quarterback, but you don't necessarily need to get one in the early rounds. Waiting on a Quarterback is more often than not a wise choice, as there is plenty of value in the mid to late rounds. And if you do go QB early, you better hit on that pick. A dud on a quarterback in the early rounds is far more likely to crush a teams chances.
