OK, but that's the problem.
Snyder's incompetence is well know. He knows nothing about how to identify talent, much let alone identify people who know how to identify talent. But that, in it of itself, is nowhere near a "sell the team" worthy notion.
People are merely using this as a catalyst to tie a bow around all the reason why Snyder should sell, including the fact that he literally doesn't know how to put quality product on the field. A valid problem for fans, but not anywhere near the level of "removal of power".
The one thing he does know how to do, is raise valuation, which he has done. You could argue pretty much every NFL team has done that in the last 20 years, but the Redskins are still among the top 5 most valuable NFL franchises, despite the fact that they never win anything.
For me, this article identified nothing other than what we already knew... he's incompetent, he's a bad owner, and the dream is that he sells. He's Peter Angelos, with less tenure, and is actually less of a POS.
