I would start Cutler over RG3 now since I learned of the team win rule. Might have even started him over RG3 anyway but now it's a certainty imo. Bears are sick and the Skins will be awful.
Try to use the rule to your advantage. It's an extra td a week. I would think of trading Newton for someone like Ben and maybe a running back that you desperately need. It's a drop off but with the Steelers being a great team and panthers being mediocre, how much is it really? And if you can add a RB on top of that? No brainer imo.
Or maybe Newton and another player for Brady? The Pats schedule is a joke this year once again. Just throwing ideas out really would need to see other rosters to have more realistic proposals.
The other bonuses are minor and won't happen as much but 5 points is a lot and there's a good chance that it can be rewarded each week for each player. It probably will effect the outcomes of games each week. You have to account for that one and get some players on great teams. Gronk is a good start.
