Here are my thoughts on the scoring:
I'd agree with the following stuff...
Rushing Touchdowns (6)
Reception Touchdowns (6)
2-Point Conversions (2)
Offensive Fumble Return TD (6)
Field Goals 0-19 Yards (3)
Field Goals 20-29 Yards (3)
Field Goals 30-39 Yards (3)
Field Goals 40-49 Yards (4)
Field Goals 50+ Yards (5)
Point After Attempt Made (1)
Sack (1)
Interception (1)
Fumble Recovery (1)
Touchdown (6)
Safety (2)
Block Kick (2)
Kickoff and Punt Return Touchdowns (6)
Passing Yards (50 yards per point; 1 point at 300 yards)
Rushing Yards (10 yards per point; 1 point at 100 yards)
Reception Yards (10 yards per point; 1 point at 100 yards)
Return Touchdowns (6)
Field Goals Missed 0-19 Yards (-1)
Field Goals Missed 20-29 Yards (-1)
Field Goals Missed 30-39 Yards (-1)
Field Goals Missed 40-49 Yards (-1)
Field Goals Missed 50+ Yards (0)
I disagree with these...
Interception (-1)
Fumble (-1)
Passing TDs (4)
And I think that they should look like this:
Int (-2)
Fum (-2)
Passing TD (+6)
If we are going to be giving yardage bonuses than I think we need to up the turnover penalty a bit. In the case of a running back a fumble should cost more than just the point equivalent of 10 yards of rushing. If a back were to have 100 yds rushing with a TD, he would be getting 17 points. That's a pretty big score for one player for close to a typical days work for a good #1 back. If that player were to however have 3 fumbles lost that game as well they should lose more than just 3 points... Turnovers really hurt teams in game and I think we should be penalized for them too. I'd kind of like to see the value of Passing TDs raised up to +6 as well, but if no one else wants that I could live with them set at 4.
I liked JediJman's defensive scoring suggestion, but would tweak it a little bit:
Points Allowed 0 points (10)
Points Allowed 1-6 points (4)
Points Allowed 7-13 points (2)
Points Allowed 14-20 points (1)
Points Allowed 21-27 points (0)
Points Allowed 28-34 points (-1)
Points Allowed 35+ points (-2)
I've played in a league where we had scoring like that, and I enjoyed it. A defense can have a great game in real life and completely shut the opposing team down, but if they don't get sacks, fumbles, or INTs we don't get squat for it.
