Do you think putting blog posts on the root poses a disadvantage?

Root: exmple.com/post-name/

Folder: example.com/blog/post-name

Site A Root

• /services/

• /about/

• /contact/

• /blog/

• /post1/

• /post2/

• /post3/

Site B Root

• /services/
• /about/
• /contact/
• /blog/
• /post1/
• /post2/
• /post3/

Do you think Google potentially would treat these two sites differently in anyway?
