The only thing that Bradley Beal does better than Brown is shoot and score. But then again, Beal has been given the #1 or #2 scoring role since being in the league. Brown did that for 1 year at age 21.
Here is a look at both players' first three seasons. Not a huge difference when you iron out the minutes in per36 numbers.

In hindsight, if Washington gave up on Beal after three seasons, like some want the Celtics to do to Brown, it would have been a huge mistake, much like this scenario would be.
Apparently Beal was able to develop but Brown shouldn't be given that opportunity because Kemba Walker is 29. Listen, this team is not in win mode now because Danny signed Kemba. They are on the way to win now mode but they are more in "let's win while developing youth mode." Clearly if Danny had this team in win mode the bench wouldn't consist of so many inexperienced players looking to develop. Besides 4th year Brown and 3rd year Tatum, this team has:
RWilliams little used 2nd year player.
Edwards rookie
Langford rookie
GWilliams rookie
Poirier rookie
Fall rookie
Green rookie
Strus two way rookie
Waters two way rookie
Wanamaker little used 2nd year player
Theis 3rd year
This is not the bench of a team trying to win now. It just ain't. If Ainge wanted to win now the roster would have been filled with role playing vets, not inexperience rookies and 2nd year players.
As for trading for Love. He is 31 years old and signed for the next 4 years at $30 million. I would rather pay Jaylen Brown $120 million over the next 4 years than Love. I would expect that Jaylen at 23 will be a better player than Love over the next 4 years. Love is already showing major signs of having a diminishing return on that contract.
I have no problem trading Brown or Tatum for that matter. But it has to be for someone significant, not meh former All-Stars. Brown or Tatum or Hayward could become meh All-Stars. What the team needs is a real superstar, and there just isn't one on the market. So, in the absence of an available superstar, you keep and develop Tatum and Brown hoping, at the least, they become meh All-Stars, but at the most, develop into difference making superstars.
