10 team Yahoo PPR w 3WR and increased points for defenses allowing <14 pts. 30 transaction limit for the season. Looking back at my past leagues I've typically averaged something like 40 moves each season, largely because I like to stream Ds. With limited transactions, should I spend a couple bucks extra for a (theoretically) reliable D? Should I take two Ds in the draft, allowing myself a little more flexibility during the season w/o having to make as many pickups? Does it matter?

Wouldn't draft two. Maybe willing to bump up my amount on a DEF but I'd be more concerned with balancing my bench and targeting guys who've been consistent, i.e. not injury prone. Would make me a bit conservative when it comes to health risks but wouldn't truly change my strategy.

I agree, i wouldnt change my strategy and i'd still Stream D's, although i would be more careful when selecting D's to stream. Maybe pickup one that has a stretch of favorable games or make sure to get in on a solid D that drops. Spend a couple bucks on a D that has a favorable schedule to begin with to get you started like a PHI or something..

Good luck!
