Fantasy football playoffs are in full swing.

You’ve made it this far in your league, and now it’s time to take your team to a new level. While you might think tinkering with your lineup at this point is a bad omen, there still are a number of serviceable players on the waiver wire who can help carry you through the postseason.

So, which players are worthy of picking up entering Week 15? Here are the best players at each position owned in 65 percent or less of Yahoo! fantasy leagues.

Quarterback: Nick Foles, Philadelphia Eagles (1 percent owned in Yahoo! leagues)
The Eagles fear Carson Wentz tore his ACL on Sunday, and even if his injury is less severe, he’s probably not suiting up in Week 15. That thrusts Foles into the spotlight. The backup QB completed 6 of 10 passes for 42 yards while filling in for Wentz, as Philly continued to throw the ball without its star quarterback. The Eagles play the woeful Giants next Sunday, so regardless of whether you own Wentz, Foles is the top streaming play at QB this week.

Other quarterbacks to target: Mitchell Trubisky (CHI), T.J. Yates (HOU), Blake Bortles (JAX)

Running Back: Rod Smith, Dallas Cowboys (13 percent owned)
The Cowboys miss Ezekiel Elliott, but his backups have risen to the occasion in his absence. While Alfred Morris receives a good chunk of the touches out of the backfield, Smith currently is Dallas’ most versatile back. The third-year back hauled in five receptions for 113 yards with a touchdown while also rushing for 47 yards and a touchdown on six carries Sunday against the New York Giants. Elliott is eligible to return in Week 16, so Sunday’s matchup against a weak Oakland Raiders defense probably is your last chance get a strong game from Smith.

Other running backs to pursue: Theo Riddick (DET), Wayne Gallman (NYG), Javorius Allen (BAL)

Wide Receiver: Tyrell Williams, Los Angeles Chargers (35 percent owned)
The Chargers’ offense has been absolutely on fire amid the team’s four-game win streak. Keenan Allen is putting up out-of-this-world numbers of late, but Williams is a strong No. 2 option for quarterback Philip Rivers. Williams had a big day in Week 14 against the Washington Redskins, catching four passes for 132 yards with a touchdown. He’s a strong vertical threat, which creates a welcoming matchup in Week 15 against a Kansas City Chiefs team that has struggled to limit big plays.

Other wide receivers to target: Kendall Wright (CHI), Tyler Lockett (SEA), Dede Westbrook (JAX)

Tight End: Trey Burton, Philadelphia Eagles, (8 percent owned)
No Zach Ertz? No problem. The Eagles were without their start tight end against the Los Angeles Rams due to a concussion, but Burton filled in and then some. The fourth-year tight end helped lift Philly to victory with five catches for 71 yards and two touchdowns. Ertz could return in Week 15 against the New York Giants, but even if he does, Burton still should receive a fair number of targets. And while Wentz likely will be out of action for Philly, Foles has thrived with the Eagles in the past.

Other tight ends to target: O.J. Howard (TB)
