Another important note regarding yardage is that it is cumulative. This means that if Jamal Anderson had 458 yards rushing total for the year so far, and this week he rushes for 82 yards, you receive 9 points from those yards. Because the first 2 yards put him at 460, which scored you a point regardless of whether you had him for any or all of those 458 yards. The remaining 80 yards scored you the usual 8 points. While this may be minute, this can be a factor in the strategy of transactions.
Players can score in many different ways.
Running backs can score points for rushing yards, receiving yards, TD s scored, passing yards, TD s thrown, etc. Basically, everyone on offense is eligible for every offensive category mentioned above. However, special teams points do not count. He will however receive any and all points at his receiver position. The more points your players accumulate, the higher your team places within your division and in the country.
