This was the first play of the game so there was an obvious pre game scout as to why they chose this tree route. I can’t know for sure but my best guess is the play was designed for HH to read the safety and throw accordingly.
That said, the safety kinda sat in no man’s land allowing both TE and WR to be open. The systems I played in and how I was taught was to check deep and work progressions back. Since HH is seeing the safety sit, WR would be the throw, however, a good pass to Fidone was fine too. HH did neither.
Im going be Memory, but didn’t Rhule even say the first play should have been a touchdown?
