David Wilson, RB (NYG)--After finding the end zone three times on Sunday, David Wilson has resurfaced as the top waiver wire pickup this week. Wilson finished Week 14 with 327 all-purpose yards, which was a team-record, including 100 yards rushing on 13 carries. Teammate Ahmad Bradshaw is scheduled to undergo tests on his knee, which could result in a heavier workload for Wilson in Week 15 if the tests reveal anything serious. However, if Bradshaw is able to play, Wilson should still have enough fantasy value based on his production with limited carries. Earlier in the season Wilson was sidelined and later passed on the depth chart by Andre Brown due to a fumbling issue, but now is him time to shine given the recent turn of events, so he is worth adding in all fantasy formats.LaMichael James, RB (SF)--Although LaMichael James recorded his first carry of the season on Sunday, more carries could be in line in the upcoming weeks as the Niners grow closer to securing a playoff spot. James finished Week 14 with eight carries for 30 yards to go along with one reception for 15 yards, which was impressive for his first career game. Over the last four games, teammate Frank Gore has recorded 20 carries just one time, so it is clear that the Niners are limiting his workload to try and keep his fresh for the playoffs. That trend should continue the next few weeks, making James a solid pickup for the last three weeks of the season.Brandon Gibson, WR (STL)--With Danny Amendola unavailable in Week 14, Brandon Gibson took advantage of an increased role in the Rams passing game. He finished the game with six catches for 100 yards and one touchdown in the Rams win over the Bills. He was targeted a season-high nine times by Sam Bradford, and if Amendola is unavailable again this week, he could see similar targets in Week 15. Gibson has shown flashes of solid fantasy production throughout his four-year career, but has yet to produce on a consistent level, landing him on the waiver wire. The Rams remaining schedule is favorable, facing the Vikings, the Buccaneers and Seahawks to round out the regular season, so Gibson has a good chance of finishing his season on a high note.Jason Avant, WR (PHI)--The Eagles season may be over, but when talking about Jason Avant, his season could be just beginning. Avant is coming off a mightily impressive game in Week 14, finishing with seven catches for 133 yards in the Eagles win over the Buccaneers and has now recorded two straight solid games. Over the last two weeks, Avant has been targeted 17 times, leading the team in that category, and appears to have built a nice relationship with Nick Foles on the football field. Considering the injuries to both DeSean Jackson and Brent Celek, Avant should continue to see plenty of targets. It also helps that the Eagles finish the season with games against the Bengals, the Redskins and the Giants, all of whom have trouble against opposing wide receivers.Clay Harbor, TE (PHI)--The Eagles have already ruled out tight end Brent Celek for Week 15, making Clay Harbor the team's starter for Sunday's game against the Bengals. Harbor had a productive game on Sunday, hauling in all six balls that were thrown his way for 52 yards and a touchdown. His targets have been limited this season, based on Celek's heavy role in the Eagles passing game, but when given the opportunity, he has shown promise. The fact that he did not drop a pass last week should result in more looks from Nick Foles moving forward. The Eagles have no reason to rush Celek back into the starting lineup since their season is practically over, so expect Harbor to finish the season as the team's starter, making him a solid pickup in all fantasy formats. Tony Scheffler, TE (DET)--Behind Calvin Johnson, Tony Scheffler was targeted the second-most on Sunday's loss to the Packers and has now been targeted 31 times in the last four games. Starter Brandon Pettigrew injured his ankle in the first quarter on Sunday and did not return to the game, opening the door for Scheffler to increase his role in the offense, and is now scheduled for tests in the early part of the week to determine the severity of the injury. If he is ruled out for Week 15, Scheffler will get the start and should be targeted heavily in the Lions passing game. The team is already without three of their four top wide receivers, which has been one of the factors for his expanded role in the Lions offense, but if Pettigrew is out for an extended period on time, he can be a trusted fantasy asset for the remainder of the season.Nick Foles, QB (PHI)--Since taking over the starting role in Week 11, Nick Foles has improved each week with Sunday being the best performance of his young career. In his best game to date, Foles finished with a whopping 381 yards with two touchdowns to go along with three rushes for 27 yards and a touchdown. His performance ranked him with the elite quarterbacks in Week 15 and has a favorable schedule to round out the rest of the season, making him a solid pickup for those in need at the quarterback position. As discussed earlier in this column, Foles has taken a liking to both Avant and Harbor in the Eagles passing game, so as long as they continue to get open, Foles should continue to grow into a good fantasy quarterback. Detroit Lions Defense/Special Teams--Considering the state of the Cardinals offense, any defensive group is worth starting against them, know matter how good or bad the matchup may be. The Lions defense has underperformed this season, but in Week 15 they have a good chance of salvaging good fantasy production. In there last two games, the Cardinals have scored just six points while turning the ball over nine times, and it doesn't look like they will get any better, so the Lions defense should be picked up and started this week.
