Don't gloss over sponsorships as some sort of side game that doesn't mean anything. Sponsorships can net you more VC per game, a bonus on big, nationally televised games, and free gear. This is especially important if you aren't spending real money on VC, as the grind to improve your character is brutal otherwise. To that end, pay close attention to the choices you make in MyCareer. Each choice and action will get you more fans, more media exposure, or alter the chemistry between you and your teammates, all of which will factor into both your player and sponsorship contract negotiations.
