A TD is worth 6 points.
If the Qb throws it, it is still worth 6 points.
In all of my leagues, they are either 6 points or I try every year to go to 6 points. 4 points is arbitrary and stupid, IMO.
The intent of 4 points for passing TD's is neither arbitrary or stupid. The intent is to make the QB/RB/WR positions be more equivalent in the pointsthat they score. This makes it more interesting for draft strategy when you may be just as likely to take a QB, RB, or WR in the first round. I
think when you give 6 points for passing TD's then the QB's clearly score more than RB's and WR's, and it is almost crucial that you get a top
passer early in the draft. Since there are not 12 top passers, some teams get screwed.
4 points per passing TD gives more options to build a good team even if you have a low first round draft pick.
The theory is flawed however due to supply and demand of QBs vs S/D of RBs and WRs. However a thorough explanation of the effect of supply and demand will take this thread way too far off topic. So I will just agree with Instinctive that 4 points is stupid
For each of the past 3 years, the difference between QB1 and QB12, between 4 pt passing TDs and 6 pt passing TDs...is approximately 2 ppg. That's all. And that doesn't account for the fact that the difference is even less sometimes because if you ranked the number of Passing TDs and then ranked the number of fantasy points, the lists would not be the same.For instance, in the 2008 season Drew Brees was QB1, and Matt Ryan was QB12 in my league's scoring system (completions and incompletions become a factor, so it is by no means standard). By the FBG standard scoring, Brees was QB1 and Ryan was QB16. We'll use them anyway.
Brees: 34 TDs
Ryan: 16 TDs
34 - 16 = 18 TD difference
6 - 4 = 2 pt per TD difference
18 * 2 = 36 points
36 / 17 = 2.11 ppg
If you use Tyler Thigpen (the actual QB12 that year) and his 18 TDs...the difference is exactly 2 ppg. However, in between Thigpen and Ryan are Eli Manning and Brett Favre. 21 and 22 TDs, respectively (which means a sub 2 ppg difference).
In closing, 4 ppg is absolutely arbitrary - if you don't think it's arbitrary, then you don;t know what the word means. There was no formula used that simply spat out the number 4. Somebody said "you know, I think QBs should have lower scores, so I'll devalue their TDs. How about 4?"
In reality, it doesn't even make QBs any more or less important. RBs are more important regardless of TD value because you start 2+ RBs. WRs are more important because you start 2+ WRs. QBs are less important because the typical league only starts 12 in any given week, and there are always 32 out there starting for an NFL team.
The only way to increase or decrease QB value is to add other things to their scoring that distinguishes top QBs from bottom QBs, such as points for accuracy, or to change the number started (e.g. 2 QB leagues), or to change the number of teams in a league, i.e. a top QB is worth more in a 14 league than a 12 team league, way more than a 10 team league, but less than in a 16 team league.
Value is derived from positional scarcity, NOT pure point values. If every single RB scored 99, 100, or 101 points every week, but every QB scored a multiple of 4 from 0-128, the QBs would have more value than the RBs. Because 1 QB scoring 128 is worth more than 3 RBs scoring 101. If all three of your RBs have 101, you are getting somewhere between a 1 and 6 point advantage over the other combinations of RB scoring. If your QB scores 128, you have between a 4 and 44 point advantage over other QBs (I assume the top 12 QBs start, even though in reality the top 12 scoring QBs for a week are not always the 12 started).
So the QB is more valuable in that scenario, because there is more variability in their scoring. In reality though, it is not just a couple QBs that get 6 for all TDs...EVERY QB gets 6 for their TDs. What changes value is positional scarcity.
