Baseball and basketball are the easiest sports to "throw," ... because individuals have a much bigger impact on the game, and because it's easier to tank it while still seeming to try.
Fumbles are a.pretty easy.way and hard to know. Also the NFL is pass happy. A secondary guy on defense could throw a game easily. Almost impossible to detect. Being a redskin fan this past year they played a very good game and beat Dallas. The next.week they play a bad minnesota team and guys are running 5-10 yards open all game. Even the announcers mentioned how open the minn recievers were. Easy throws for a mediocre QB. Redskins lose a close game. I call lack of effort throwing games too. Games are thrown every week in the NFL. There is point shaving going on in the college ranks too. Probably a lot more than fans would want to know about, and games.being fixed.
