New Fan here. What do i have to know?

I'm a Thunder and Rockets Fan in the NBA, and Harden is my favourite Player, so i decided to watch the Texans as my Team, since OKC doesnt have a NFL Team.

What do i have to know? I know Watson is a star and still young, but he is a MVP caliber player like James Harden? And how are the expectations?

Cheers!
