With D/STs, you should be prepared to stream in most leagues. D/ST is the most obvious fantasy position to stream, since the score is mostly dependent on the opposing offense—thereby affecting each D/ST’s value every new week.
Many people try target defenses to hold, but you'll run into a few problems:
at some point your D/ST will have its Bye week,
your defense will hit some tough opponents, while good streaming options pass you buy, and
the experts often wrongly judge defensive prowess before the draft.
Oh, and injuries.
You might be forced to hold a D/ST if your league has 16 teams and they hoard D/STs. Then you may also sometimes decide to play no D/ST at all for a given week (fear of negative points). But usually D/ST streaming is simply the obvious thing to do.
