As the fantasy football postseason is set to begin in Week 14, it is important to look ahead to this week and future weeks when picking your defenses to start. For those of us who don't own defenses like Seattle and Denver, it is important to look at matchups to make the best possible decisions for mixing and matching Weeks 14-17 when it counts the most.

Many people like to stream defenses, and below are some of my recommended defenses to stream for the fantasy football playoffs. These four defenses should be considered while making your lineup decisions, and they may be available in your leagues depending on the size and format. Good luck, RotoBallers.

Cincinnati Bengals Defense (D/ST)

Owned in 50% of Fleaflicker leagues

The Bengals defense starts out with a no-brainer start in Week 14 against the Browns abysmal offense. In Week 15 for your semifinals, give them a seat on your bench as they play a tough Steelers offense. Plug them right back into action in Week 16 for the finals against a Houston Texans offense that has been struggling with Brock Osweiler at the helm.

Atlanta Falcons Defense (D/ST)

Owned in 7.5% of Fleaflicker leagues

The Atlanta Falcons aren't exactly known for their tough defensive prowess this year. However, they have very favorable matchups in the first round and semi-final game. In Week 14, they play a terrible offense in the LA Rams with rookie QB Jared Goff still going through growing pains. In Week 15 they come across the 49ers at home who are 1-11 and can't figure out which QB to start.

Buffalo Bills Defense (D/ST)

Owned in 55% of Fleaflicker leagues

After a tough matchup in the first round in Week 14 against the Steelers, the Bills play the winless Browns and a below-average Miami Dolphins offense both at home in Weeks 15 and 16, respectively.

Miami Dolphins Defense (D/ST)

Owned in 57% Fleaflicker leagues

The only solid matchup the Dolphins have in the playoffs is in the semi-finals against the Jets, who will have struggling second-year QB Bryce Petty calling plays. The Jets offense could be even worse than the Browns at this point. Look for some potential pick-sixes.
