#2 Daniel Bryan can get the adulation of the fans and grow his legend if he faces The Rock

Even though Daniel Bryan has faced a lot of WWE Superstars who are guaranteed future Hall of Famers, he has never faced someone with the star power that The Rock possesses. The Rock who is justifiably nicknamed as 'The Great One' for being an all-time great, can provide Bryan with the opportunity to become a great in his own right by stepping in the ring with The Rock.
Even though the likes of Triple H, Randy Orton, Batista, and John Cena have "put over" Bryan in matches, none can match the charisma and the presence of The Rock.
If The Rock returns for one final match to face Daniel Bryan, the latter can have the chance to give a proper send-off to The Great One and can add another name to the list of greats he has defeated. The Rock himself was "put over" by The Immortal Hulk Hogan at WrestleMania 18 in 2002, so it only seems fair for him to put Bryan over.
