I mostly play SF, but I like 6pts for TDs and -4 for interceptions because it's been the most effective way I've seen of promoting high value on the actual good QBs while not pumping up the value of just every QB. Typical -1 or -2 pts for interceptions still leaves you jamming any QB you can find into the SF slot.
-4 will actually have you considering whether throwing in a guy like Daniel Jones or Jameis Winston in his crazy high turnover year over a flex RB or wr is a good idea.
What penalties are assessed for players when they fumble? Anything for when a receiver runs the wrong route causing an interception?
Is anyone deducting points from a WR running the wrong route in a league with -1 or -2 point deductions for interceptions?
Some leagues deduct for lost fumbles.
I would guess most do. I touched on this briefly at the end of post #14, but it's definitely logical for a lost fumble deduction to equal the interception deduction. I wouldn't fault anyone for not moving off of that. In practice, I'm comfortable leaving lost fumbles alone (-2 for me) -- even in a scenario where I'm increasing the interception penalty from -2 to -4. I'm fully aware that the majority of fantasy players aren't going to like the concept of -4 interceptions, even though I think it's justified when comparing interception count to passing TD count. No respectable QB or head coach is accepting a 1:1 TD/INT ratio.
I'm even more certain that changing lost fumbles from -2 to -4 would be less popular with the fantasy masses. Given that there's fewer lost fumbles than interceptions, I'm probably okay leaving this hornet's alone. However, in theory, lost fumbles
should equal interceptions. It's a comparable sin, maybe more egregious and less likely to be the fault of a teammate.
In my 1/2 PPR scenario, where I'm trying to balance the superflex option between QB -vs- WR/RB/TE. I would fully endorse this format:
passing TDs = 4
interceptions = -4 (from -2)
lost fumbles = -4 (from -2)
rushing/receiving 1st downs = .5 (previously unscored)
RB/WR/TE (or QB) is picking up an extra point to 2.5 points per game on first down scoring, but they're also going to pay the price when they cough up the ball. It's not going to be everyone's cup of tea, but for those that want fantasy scoring to better reflect in-game performance, it's probably a step in the right direction.
