The All-Pro by Scott Sigler
This is a great series of books. The football aspect of it is spot on. Sigler knows his stuff and does a great job of giving you an idea of what it would be like to line up behind center and look into the eyes of someone (or something) determined to end your career every play. The idea that football might still be played 700 years into the future by not just humans, but by elite athletes from all the sentient races, makes the series all the more enjoyable. It's a lot of fun and fans of either the sport or the science fiction genre should enjoy it a lot.
