Agree with the starting 5. But I think Hayes is more ready to contribute than Blatche. E Thomas also will be a key reserve, that will give you 9 deep in the regular rotation. But we need Sonfaila to be healthy, plus Thomas and Hayes to "stay healthy" (they have difficulty to do so in the past).
The problem with replacing Jeffries with Stevenson in the staring lineup is that, last year they are 7', 6'11", 6'9", 6'7", and 6'4" (ranked from tallest to the shortest), that's a pretty tall lineup. This year, they are 7', 6'9", 6'7", 6'5" and 6'4". If Haywood is replaced by Thomas as some have suggested, then they will be 6'10", 6'9", 6'7", 6'5" and 6'4", pretty much shorter than the opposing team in all positions but PG in any given night. (Phoenix is an exception, but Nash makes it work, while Arenas is a different type of guard.)
In addition, Jeffries is a good offensive rebounder, so their second chance scoring opportunity will be reduced. OTOH, Wizards also gave out tons of offensive rebounds, the personnel change alone certainly did not address this issue (i.e., no bulky PF who takes up space). Hopefully, they can make a better, conscious effort in blocking out opponent rebounds.
