Who should I start this week!! and who should i drop?

If you have limited moves, it's not worth it dropping your defense, but losing by 3 points could happen and not having a position played could cost you. If you're willing to drop PHI defense and risk another team picking them up for a few points this week, then go for it. As your flex, I like Torain's matchup against DET, but LT is becoming one player that you just don't want to bench. I would start LT based on the year he is having.
