The Touchdown Gene by Thomas Hoover
Genetic manipulation can be a wonderful thing; but what happens if you do it to an NFL football team? Nolan Pharmaceutical was a company in trouble. So were the New York Wolverines, an NFL franchise that had fallen on hard times. Together, perhaps they could solve both of their problems; but it was to be a marriage made in hell. Sequestered on the Caribbean Island of Bonaire, the Wolverines held their normal pre-season training camp, with one exception. Nolan Pharmaceutical was experimenting with DNA manipulation to enhance the player's performance in a way that could not be detected by any drug test. Everything was going well until the lead scientist did the unthinkable. He started splicing in genes from predatory animals.
