First week has been a bit dull with the exception of Zverev's matches, except even those aren't even that surprising considering he seems to do this every major.
That said, I actually think Nadal's second week, starting with the quarter finals, won't be THAT straightforward. Schwartzman won't beat him, obviously, but he won't go down easily, and I think the semis will be more intriguing than people seem to be suggesting. Both Cilic and DelPo are good semi final opponents. One of Thiem, Zverev (unlikely) or Djokovic (very possible) will be in the final so at least there's that to look forward to.
