He should be back in the good graces of all fantasy fans against the , though.

His succe s should continue on the road, where he's been a real stat-sheet stuffer. In fact, Olsen has caught at least five pa ses in each of his last four roadies. He's also scored four touchdowns in his last six road contests.</content:startem-sitem><content:startem-sitem startsit="start" type="player" playeresbid="ERT800920" oppteamabbr="SF"> This isn't a favorable matchup on paper, as the Niners have allowed an average of just 5.10 fantasy points to tight ends this season. Still, this defense has not been impenetrable. In fact, the Niners have surrendered eight touchdown catches in their last four home games. That's enough for me to start Ertz in what could be a shootout.</content:startem-sitem><content:startem-sitem startsit="start" type="player" playeresbid="BEN379259" oppteamabbr="GB"> Bennett has a trend of finding a lot of succe s in September, as he has recorded an average of 58.7 Orlando Cepeda Jersey yards per game and a combined 10 touchdowns in his last 11 contests ( -- seven games, -- four games) in the month. If you don't have an elite fantasy tight end, Bennett is well worth a start based on his overall September succe s.</content:startem-sitem><content:startem-sitem startsit="start" type="player" playeresbid="WAL115671" oppteamabbr="IND" extra="sleeper"> Walker has been a pleasant surprise for fantasy owners, ranking fifth in points among tight ends over the first three weeks of the season. He has a nice matchup in Week 4, as he'll face a pa s defense that has surrendered three touchdown catches and the fifth-most fantasy points (12.87 Mike Yastrzemski Jersey PPG) to opposing tight ends in 2014.</content:startem-sitem>Sit' Em Miller has been all but invisible, posting no touchdowns and a combined 9.20 points over the first three weeks. Next on the schedule is a date with the at Heinz Field. In his last 10 home games against the NFC, Miller has posted 70-plus yards just three times. He has also scored just one touchdown in those contests.</content:startem-sitem><content:startem-sitem startsit="sit" type="player" playeresbid="KEL012458" oppteamabbr="NE"> Kelce will be a hot Brandon Belt Jersey name off the waiver wire this week, as tight ends have dropped like flies around the NFL. However, don't be shocked if he fails to make a lot of noise against the . Their defense has surrendered an average of 4.37 fantasy points per game to tight ends this season, so Kelce is no lock to put up good numbers.</content:startem-sitem><content:startem-sitem startsit="sit" type="player" playeresbid="DAN576298" oppteamabbr="CAR"> Daniels figures to see more targets with now on the sidelines, but that doesn't mean he's a guarantee to post solid totals. This week he faces the , who have held opponents to two or fewer touchdown catches eight times in their last nine road games. That includes six games with one or fewer scoring catches.</content:startem-sitem><content:startem-sitem startsit="sit" type="player" playeresbid="FLE075352" oppteamabbr="TEN"> If you started Fleener last week, you were Burch Smith Jersey rewarded with 49 yards, one touchdown and 10.90 fantasy points. Still, Fleener isn't the tight end I trust in my leagues ... that would be . Also, the have surrendered an average of just 6.20 fantasy points per game to tight ends, including games vs. Kelce and Witten.</content:startem-sitem><content:startem-sitem startsit="sit" type="player" playeresbid="WIT559021" oppteamabbr="NO" extra="beware"> Witten is likely to be active in most fantasy leagues, as the tight end position has become thin due to injuries. Keep in mind, though, that he has been held in check by the during his career. In seven meetings, Witten has been held to 60 or fewer yards six times. He has also never scored a touchdown against New Orleans.</content:startem-sitem>Michael Fabiano is an award-winning analyst on NFL.com and NFL Network and a member of the Sports Writers A sociation (FSWA) .
