It should be no surprise that the top defense/special teams (DSTs) for Week 15 are those that face opponents that have typically allowed a lot of fantasy points to their opponents. Teams like the San Francisco 49ers, the New York Jets and the Cleveland Browns are well out of the playoff hunt and have given up on the season. That bodes well for their opponents.
Along those lines, the Buffalo Bills (vs. Cleveland) are owned in 62 percent of fantasy leagues, so that DST may be available for those looking to stream for Week 15. The Houston Texans (vs. Jacksonville) are available in about 45 percent of leagues, and are another good option for Week 15.
