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.
-Gus Johnson played 9 seasons in Baltimore. He mae the All-Star team 5 times, 4 All-NBA second teams and 2 defensive teams. Helped Baltimore reach the Finals.
-Earl Monroe played his early career in Baltimore, He made 2 All-Star games and 1 All-NBA 1st team. Also helped Baltimore to the NBA Finals.
-Wes Unseld played for the Bullets his whole career. Baltimore, Capital and Washington. Won MVP his rookie season and All-NBA. He m,ade 5 All-Star appearances and 3 Finals before finaly winning in 1978.
-Elvin Hayes played a bulk of his career for the Bullets, 9 pf his 16 seasons. In those 9 seasons, made 8 All-Star appearances, many All-NBA and won a title.
-Gilbert Arenas has played the last 4 seasons as a Wizard. Has made 3 straight All-Star appearances and 3 straight All-NBA teams. Took the Wizards also to 3 straight playoff births. Hasn't happened since Wes and Big E were playing.
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).
