Yeah shanks really is oda self insert, no doubt about it, he won't let shanks look bad even if it hurts the story
It hurts the story people have told themselves about Shanks. He is one of 4 Strawhat wearers, along with Roger, Luffy and Joyboy. People seem to think he is the odd one out in that equation-he isn't.

All this buildup for Shanks is to make Teach look like an insurmountable obstacle when Shanks loses to him.

Shanks can only lose to Luffy or Teach. No one else.
 
- After Whitebeards death Shanks received the title World Strongest Man
- Even the Giants respect him for his strength, we get a small flashback of Shanks as a teen training in Elbaf
- The Giants also talk about how Shanks became a Yonko 6 years ago
- The crazy technique he used to defeat the previous Yonko has really put him on a pedestal of his own
- Only the Pirate King Gol D Roger ever came close to that kind of strenght
