By selling courtside spots, several NBA teams can now squeeze in 20 percent more seating at their games. This advice comes from Weekend Journal's Sam Walker, who appears weekly on ESPN News' "Bull and Bears" (Thursdays, 5 p.m.-7 p.m.):

Dallas Mavericks: Floor seats run $240 to $2,200, but scalpers and fans sell great seats at face value.

Seattle Supersonics: Floor seats go for $150 to $625. The Sonics are one of three NBA teams that let season ticket holders sell seats online, even at a discount.

New York Knicks: Fans can pay up to $1,600 for courtside seats, but you can sit behind the baskets, front row, for as little as $100.
