Would like to see qbr rating and completion percentage added as a scoring option ,for too long yahoo had the same scoring options
You can come close to putting a completion percentage into your league.
Have your Commish add something like +1 for each completion and -1 for each incompletion.
Or, maybe you'd prefer +1.5 or +2 per completion and -1 for each incompletion.
Or, maybe you'd prefer +1 per completion and -.5 per incompletion.
Play with the numbers a bit, and you should find what is right for your league.
