Should the Wizards go Swingman at 6 and then a Big or vice versa?

We could get a SF like K. Leonard or Jan Vesely with the 6th pick and then a quality big with the 18th pick. Or we could get Jonas(don't know how to spell his last name) or Biyombo at 6 and then draft a SF like Tobias Harris or Tyler Honeycutt at 18. I'd go the first option but alot of people don't trust Andray Blatche and think we should get a big man early to boost our frontcourt.
