my league awards a 0.5pts for both 'tackles for loss' and '3 and outs forced'. Does 4for4 predict these? And which teams would be the best to get these stats
Those are a little more granular than our full impact goes. However, those are both affected by total yards allowed, so I might do something like 5 points for under 300 yards allowed per game, 3 points for under 325, 0 for under 350, -3 for over 375, and -5 for over 400. Not a perfect solution, but should up the value of teams like Denver and Seattle, and decrease the value of teams like Carolina and Kansas City who do a bit more "bend-don't-break."
