Where can I buy and watch full episodes of the Playmakers (football show on HBO)?

You can buy the dvd series on Amazon and watch them anytime you'd like, however the series is an ESPN feature.

It depicted the lives of the players of the Cougars, a fictional professional football team in an unidentified city. The show starred Omar Gooding, Marcello Thedord, Christopher Wiehl, Jason Matthew Smith, Russell Hornsby and Tony Denison. The show, which ran eleven episodes from August 26, 2003 to November 11, 2003, was the first original drama series created by ESPN. Though it had a critically acclaimed cast, it was criticized for predictable and often sensationalist storylines, while simultaneously praised by publications such as Tv Guide and Entertainment Weekly. The show dealt with topics including drug abuse, steroids, domestic abuse, and homosexuality. The NFL was unhappy with the way the show portrayed professional football players (despite several players, most notably, Deion Sanders, speaking out about the accuracy of the lifestyles portrayed), which prompted ESPN to cancel the show out of fears of having their TV rights to the league revoked.
