Trevor Ariza ain't making any bold predictions about his new team ... 'cause when he landed in D.C. after being traded Sunday -- he told TMZ Sports he has no idea if the Wizards can win the East!!!
Ariza was sent packing by the Suns in a trade over the weekend ... and when we got the NBA star after he touched down at Dulles -- he said he has no expectations for his new squad yet.
"Shoot, I don't know. I'm just getting here, bruh!"
Seems Trevor's already a good luck charm .
