No. Not in the NFL, only in college football
Half the distance is used when a penalty has occured and the yardage that is penalized is longer than half the distance to the goal. Example: a team is on their own 10 yard line and they have a 10 yard holding penalty. 10 yards would put them in their own endzone, but they would penalize half the distance and they would start the next drive on their own 5 yard line.
You cannot decline the penalty, since it is happening prior to the snap, you can, however, decline the YARDAGE of the penalty.
yardage markers
If the penalty is assessed against the defense, the ball will be moved that number of yards toward the goal, or half the distance to the goal, whichever is less. the same applies in the opposite direction, except that it's highly unlikely that half the distance to the goal behind you will ever be less than the penalty yardage unless there are a lot of consecutive penalties on first down or the QB is an idiot and runs the wrong way before getting penalized. In any case, a dead-ball foul will cause first-down to be replayed with the modified yardage to go (usually 5 or 15, but depends on the penalty assessed).
You need to be more specific. Total yardage in a single game? Total yardage in a season? Total yardage in a college career? And is it rushing yardage, passing yardage, kickoff yardage, puntyardage, kickoff-return yardage, punt-return yardage, total return yardage, or total yardage. If it's passing yardage, do you mean as a receiver or as a passer?Of course, I don't know the answer either way, and really, who cares? It's Division II. It could be a million yards, but whoever holds the record can't hold a candle to the average division I-A player. If they could, they would have played in Division I-A, or at least I-B.But if you want anyone to answer this question, you're going to have to be more precise in how you ask it.
45 yards...there's no penalty for a missed pass.
76
to add and subtract yardage
yes, in college football. In the NFL sack yardage is taken away from the team passing total. It has no affect on rushing yards.
93 yards is the longest thrown yardage in history
56 yards
