There are lots of good choices here and it is definitely tough to select just one.
While I am one who certainly wants to see everything Commanders go, I will say this - I survived the last several seasons watching this team go by a name other than Redskins WITH Dan Snyder still in charge. If I could survive that as a fan and still maintain interest in the football product, I am sure I can survive having to be called 'Commanders' with new ownership, even if I don't like it. One thing I will add on that front is that if we can somehow fix the uniforms to resemble more of the classic Redskins look, I think it will make many more Redskins fans like myself start to come around and eventually accept the name down the road...maybe.
Winning cures all ills though. We win, and people will be quick to forget or care that we are the Commanders now. With that in mind, bringing in football people and a proper GM has to be near the top of the priority list.
The good news is that there is a history of this with Josh Harris' other sports ventures. While I am not really a basketball guy, Harris brought aboard Darryl Morey to the 76ers, who oversaw the Houston Rockets have the 2nd best winning percentage over the course of his 13 seasons running that team as GM. Being Canadian, I am more familiar with his hockey venture - the New Jersey Devils. There, Harris brought in Ray Shero to run the Devils as GM for five seasons, after helping to build the Pittsburgh Penguins into a Stanley Cup winner in 2009. For a while, Shero was a very well-respected GM in league circles and Harris was able to bring him to Jersey. Let's hope Harris follows suit in Washington.
