The fantasy football season is off and running. Three weeks in, you may feel like you have the temperature of your team, but truth be told -- theres a lot of football left. Roster shuffling will be constant over the rest of the season, especially as bye weeks begin starting this week (and continue until Week 13), meaning you might be without a key member of your roster that you need to account for. Factoring in bye weeks, injuries and performance on the field, below is a look at our Week 4 ESPN Fantasy wavier-wire adds.As usual, all players included in this column are owned in less than 50 percent of leagues on ESPN.com.Terrelle Pryor, WR, Cleveland Browns (23.7 percent). A fixture on this list each week so far this season, Pryor exploded onto the scene in Week 3. He did it all for Cleveland, throwing five passes, adding 21 rushing yards (including a touchdown) and catching eight passes for 144 yards. An exceptional athlete who will have extensive utility in Cleveland as the Browns deal with quarterback woes, Pryor needs to be owned in all size leagues.Jordan Howard, RB, Chicago Bears (15.5 percent). There was already a bit of momentum toward Howard seeing a larger workload in Chicago, but with Jeremy Langford now dealing with an ankle injury, Howard is in line to start. He combined 47 receiving yards with 45 on the ground in Week 2, and will enter flex conversation for Week 4 with Langford out.Orleans Darkwa, RB, New York Giants (5.0 percent). Theres a double dose of injury news in the Giants backfield, as Shane Vereen is on injured reserve because of a triceps injury, while Rashad Jennings missed Week 3 with a hand issue. While Darkwa wont have the job to himself if Jennings misses Week 4, hes the first name I would add among fill-in Giants running backs. He had 11 touches in Week 3.Bobby Rainey, RB, New York Giants (0.0 percent). Rainey played eight snaps in Week 3 and has experience in previous stints with different teams as a capable pass-catching back. While Paul Perkins could see work given the injuries to the Giants backfield, it seems Rainey is the more likely option to help account for Vereens role in the near future. Hes worth adding in points per receptions leagues of 12 or larger.Carson Wentz, QB, Philadelphia Eagles (19.3 percent). Three incredible weeks of Wentz has been the talk of the town in Philadelphia -- and justifiably so. He has been remarkable, and despite the fact that he heads into a bye in Week 4, he needs to make this list. Hes a capable fill-in for your current starter in future bye weeks and a streamer when your starter has an unfavorable matchup. From a dynasty standpoint, one can make the case that he has as much long-term value as any quarterback drafted in 2015 or 2016.Cole Beasley, WR, Dallas Cowboys (14.5 percent). Dez Bryant is dealing with a knee injury now, but it remains to be seen if it will cost him any time on the field. But Beasley has been a clear part of this offense so far in 2016, tallying 20 catches in three games. Thats good enough to squeeze him into this column again. Hes a starting-level player in 12-team or larger points per reception leagues.Darren Sproles, RB, Philadelphia Eagles (49.3 percent). Sproles has been so good for so long, but the role in Philly this season is particularly enticing. He led the Eagles in targets in Week 2 and is a useful add to your lineup in points per reception scoring. He has seen some work in the red zone, too, this year -- critical for fantasy value.Jamison Crowder, WR, Washington (11.1 percent). Crowder is a slot machine for Washington, but he has been a major red zone target as well this season. He has eight red zone looks through three games, a robust total and enough to consider his upside as higher than simply a PPR-league asset. Washingtons offense got back on track in Week 3. Crowder should be owned in any PPR leagues and standard leagues of 12 or more teams.Dwayne Washington, RB, Detroit Lions (20.4 percent). With Ameer Abdullah out for the year, Washington figures to hear his name called much more going forward. The running game was anemic for Detroit in Week 4, but until we see the team either make a move to add another back or use Zach Zenner over Washington, he needs to be added in 12-team or larger leagues. Detroit still figures to be a pass-heavy offense.Kyle Rudolph, TE, Minnesota Vikings (40.6 percent). The 7-70-1 line from Week 3 from Rudolph was nice, but theres one stat that stands above the rest to highlight his value: 26 targets in three games. Perhaps that pace will slow a bit, but Rudolph is currently on target for just under 139 this season. His size, catch radius, red zone ability and workload are enough to add him as a starting tight end. Hes a very good player.Wendell Smallwood, RB, Philadelphia Eagles (1.4 percent). Another Eagle (theres a theme to this list, it appears), Smallwood burst onto the scene in Week 3 after Ryan Mathews dealt with an ankle issue. Smallwood, a fifth-round pick this year, showed well in the offseason and tallied 79 rushing yards on 17 carries (including a touchdown). He ran too well to ignore. His value will be mitigated by Mathews return (well see in Week 5), but hes intriguing.Kenyan Drake, RB, Miami Dolphins (30.5 percent). With Arian Foster uncertain for Week 4 (its a short week for Miami), Drake will be an oft-discussed name leading up to the Thursday night game with Cincinnati. There wasnt much to inspire confidence from any Dolphins backfield player in Week 3, but if you play in a 16-team league, Drake is a player to consider.Victor Cruz, WR, New York Giants (47.4 percent). Another repeat player in the column, as weve discussed Cruz as a worthwhile add in points per reception leagues (he has been in double digits each of the first three weeks in PPR formats). Hes also excellent insurance as a handcuff to?Odell Beckham Jr.?or?Sterling Shepard. The Giants rely heavily on all three wideouts.Hunter Henry, TE, San Diego Chargers (12.0 percent). Antonio Gates didnt practice all week or play in Week 3, opening the door for Henry to take every snap against the Colts. He managed five catches for 76 yards, but a fumble put a bit of a damper on his day. All that being said, his workload should be steady if Gates misses more time. Hes a usable tight end until Gates comes back.Trevor Siemian, QB, Denver Broncos (4.7 percent). This isnt an overreaction to Siemians incredible Week 3 showing, its a reaction to his standout play and other pertinent factors going forward. Siemian was awesome against the Bengals and now faces a generous Tampa Bay pass defense. If you are an Aaron Rodgers owner looking for a bye week fill-in or a concerned Russell Wilson owner (due to his injury), Siemian is an intriguing Week 4 streamer.Robert Woods, WR, Buffalo Bills (2.2 percent). If you play in a deep, PPR league and are looking for a fill-in in case Sammy Watkins misses another game, Woods is on the radar. He had six catches on eight targets in Week 3. The Bills offense bounced back following a coordinator change made after a Week 2 game.Adam Humphries, WR, Tampa Bay Buccaneers (0.7 percent). The numbers from Humphries during the past two weeks indicate he could be the No. 2 wideout in Tampa Bays offense. Hes racked up 15 catches for 167 yards; thats plenty of production to merit consideration in PPR leagues.Jaron Brown, WR, Arizona Cardinals (0.6 percent). Fellow Cardinals wideout Michael Floyd is currently dealing with a concussion, and well learn more about his status for Week 4 as the week moves along. In the meantime, Brown could step into a No. 3 receiver role, which carries value in an offense that relies heavily on three wideouts. Hes worth an add in deeper leagues.
