The only paragraph from the article that matters:
"The reasons for the holding pattern are complicated, according to people familiar with the Lerners’ thinking who still cite lingering uncertainty over future television revenue as a remaining roadblock for any buyer. But those people say they still expect the Lerners to sell the team if Leonsis can meet their asking price. The question, then, seems to be how much higher they need him to go — and whether Leonsis, who recently bolstered Monumental Sports & Entertainment’s capital with an investment from the Qatari investment fund, will be willing to go there."
It should surprise no-one that an organization whose most valuable asset is tied up in never ending litigation is impossible to value and sell. The Lerners are stuck with the Nats unless they agree to a ridiculously low valuation which means we're stuck with owners who no longer want to own a team
