Defensive players in Fantasy

So, got myself in a new situation this season. The league I have played in for years has folded, and I just recently joined a new one. I have always played no kicker, DST, or defensive players. This new league plays a DST, DB, DP, and kicker all in the starting lineup to go along with your basic 1 QB, 2 RB, 2 WR, TE, and a Flex.

How do you go about drafting the defensive side of the ball?
Any tips appreciated,


mlb’s that are 3 down players, helps also if they are on a bad team.
