No more "NFL Dynasty" ever again.

Why?

Because it's too expensive to keep a core nucleus of good players together, especially if they are young. Bad teams usually end up with a large amount of cap space that can afford to pay (or overpay) for key role players from Superbowl squads (think Miami this past off-season). 

In the case of this year's Superbowl winning team, the Seattle Seahawks, there are just too many young players who will demand large contracts soon, (Russell Wilson, Sherman, Earl Thomas, not to mention Percy Harvin's salary hit jumps from 4.9mil to 13.4 mil next year, etc.)

In a year or two Russell Wilson will likely demand anywhere from $17-20 million where as Richard Sherman will likely get around $9-12million a year and Earl Thomas will get around $7-9million per year. Compare that to each player's cap hit this year $682,000, $600,000, $3.5mil, respectively. If using the minimum figures I proposed earlier, the total cap hit for just these three players(assuming they are going to demand top5 dollar at their respective positions) would be a rise of over $28 million in cap space.

It was easier to see the Cowboys keep their core players intact, as well as the Patriots in the 2000's because every new contract wasn't a record breaking contract like it is today. A perfect example of this would be the hefty raise for Superbowl winning quarterbacks the last few years.


Aaron Rodgers: $22.0 million per year
Joe Flacco: $ 20.75 million per year
Drew Brees: $20.0 million per year
Eli Manning: $16.5 million per year
(Peyton Manning made $19.2 million last year)

Will Russell Wilson, if he plays well into his 3rd NFL season, see a raise over $22 million? What kind of market would Richard Sherman, the self-proclaiming best cornerback in the league demand? How about Earl Thomas, one of the best young players in the game?

Only time will tell, but in the short history since record breaking contracts started to bust out (after the 2008-2009 season when the Redskins signed Albert Haynesworth to that mega-contract in the no-capped year), there haven't been good news for teams looking to become dynasties.
