Is the question about the picture or the NFL in general.
As for the picture two of the Quarterbacks (QB - Tom Brady & Drew Brees) remaining in the playoffs are ridiculously odd by traditional NFL standards. What that comes down to, is that over time, rule changes have made being a QB easier. This in terms has mainly benefited the QBs that are very talented, allowing them to play the game longer. In the 'good old days' these QBs would have had broken bodies by now and would have been forced to retire. In the case of Tom Brady this would have been a good thing.
