because the wife that knows everything about football, is blackmailing his friends, lets her husband watch porn, gets mad one night because his friends are posting stories about her *** on the league page and goes back to humping his brains out the next night, and performing "special sex" is clearly not the hottest woman on the show, physically, but for some reason she is still the hottest girl on the show.
It is like they picked someone that they know doesn't look like Marisa Miller or Sloan from Entourage, but they made her just as hot with mind tricks.
