When Jordan came back, he said it was "teaching", so it would appear he wasn't going to try to take over, just help his front office objectives. That aside, he is the only 40 year old to score 40.
At the same time, I can't remember if Webber was still around when they changed, Juwan wasn't doing bad, but Gilbert is outplaying them both. Jordan just didn't seem to have as much impact as he had hoped at first, but look at Hamilton after two years next to him. I think MJ is not the best Wizard, but Rip is proof of the impact MJ could still have at 40. Still, hard to go past Arenas. Sorry for rambling.
No matter how you look at it Michael Jordan is always going to be known as a Bull not a Wizard. He might be the best player to ever play on the Wizards because he is obviously the best player in the history of the game despite his old age when he played for them. I would put him ahead of Arenas just for now. So this is how I see it.
1. Michael Jordan
2. Gilbert Arenas
3. Rip? Antwan? Stackhouse?
-Walt Bellamy played four and a half seasons with the Wizards franchise when they were called the Chicago Packers, Zephrys and then Baltimore Bullets. He made 4 All-Star games, took them to the division finals (now called conference finals). His best season, put up 32 and 19.

This post does nothing to prove your claim that "Arenas could never measure to what Jordan did." Maybe for starters you should describe what Jordan did, and then we can debate whether Gilbert is capable of it as well.
Because as far as I can see, Arenas has already done what Jordan did with the Bulls (post similar/better stats and lead them to the playoffs).
