Did you read the whole thing?
"The modest rate of franchise value growth under Goodell has come from a very high baseline — and perhaps some decline in the rate of growth was inevitable given how prodigiously they grew under Tagliabue. In absolute dollar terms — not percentages — NFL franchise values have risen by a collective $10.9 billion since 2006, compared with $11 billion for baseball, $7.5 billion for the NBA and $6.6 billion for the NHL. The NFL is still a hugely profitable business, and even poorly run franchises tend to make money because of the league’s aggressive revenue sharing and relatively favorable contractual agreements with players. According to Forbes, only the Detroit Lions lost money in 2013, and the league’s 32 franchises earned a collective $1.7 billion in operating income."
I don't think you could put anyone in there and expect the league to grow.
