What are common mistakes athletes make in their sponsorship decks?

Common mistakes include: 1) Writing a four-page biography telling your entire life story instead of keeping it brief with pictures and a few sentences. 2) Focusing too much on your race resume listing placements at events sponsors have never heard of. 3) Sending generic proposals where you forgot to remove a previous brand's name. 4) Having a logo on your vehicle from a competitor of the brand you're approaching. 5) Showing photos with empty grandstands. 6) Not proofreading and reviewing your proposal carefully before sending.
