Normally I lead this column with a broad opening, something that applies to either the theme of the week or the portion of the fantasy football season that we have reached. This week, given the first player on our Week 8 Waiver Wire column, I'm going to address the question that so many have been -- or soon will be -- asking: Is Ty Montgomery eligible to be played in a running back slot, given his usage with Green Bay?

Here's the answer: Yes. Effective this week, Montgomery is eligible at both wide receiver and running back. It's important to note that once we add a position to a player's eligibility, it cannot be removed that season. As such, the wide receiver/running back tag is staying for Montgomery for the rest of the 2016 season.

With that cleared up, here's our Week 8 ESPN Fantasy waiver wire column.

Note: All players who appear on this list are owned in less than 50 percent of leagues on ESPN.com.

Week 8 byes: Baltimore Ravens, Los Angeles Rams, Miami Dolphins, New York Giants, San Francisco 49ers

Jacquizz Rodgers, RB, Tampa Bay Buccaneers (34.5 percent). With Doug Martin suffering a setback in his recovery for a hamstring issue, Rodgers has the starting job to himself in Tampa Bay. What has he done so far? Gone more than 100 yards on the ground in two straight games and handled 62 total touches. The volume is great, and so is the production, and the upcoming schedule isn't something to be scared of. Rodgers is a must-add in all leagues and an RB2 right away.

Ty Montgomery, RB/WR, Green Bay Packers (17.8 percent). Regardless of what position he stays at, Montgomery is an add in all leagues. He has collected 20 catches the past two games and has 12 rushes for 66 yards. He reminds me of James White in New England. Even if he tallies more receptions than rushes, those catches serve as an extension of the running game. He's a fun player to watch.

Mike Gillislee, RB, Buffalo Bills (6.1 percent). As of this writing, we don't know what LeSean McCoy's status is for Week 8 against the Patriots. But this much we do know: McCoy left Sunday's game due to an aggravated hamstring issue, and Gillislee is the next man on the depth chart. He's a must-add for all McCoy owners and a reasonable pickup in any league for someone who needs running back depth. With a Week 10 bye on the horizon, it wouldn't be a major shock if McCoy sits the next two weeks.

Matt Asiata, RB, Minnesota Vikings (26.0 percent). Asiata's value is not rooted solely in the health of Jerick McKinnon, but it's worth noting that the latter left Sunday's game against Philly because of an ankle injury. If McKinnon sits, that thrusts Asiata right into RB2 territory for Week 8 against the Bears. He already has value in deeper leagues, as he has 35 total touches in Minnesota's past two games.

Davante Adams, WR, Green Bay Packers (17.5 percent). What a Week 7 for Adams, the former second-round pick who had 13 catches for 132 yards and two touchdowns against the Bears. His stat line wont be nearly that gaudy each week, as he's going to be the fourth passing game option for Green Bay many weeks, but he has value in deeper leagues now and can be used if anything happens to Jordy Nelson or Randall Cobb.

Devontae Booker, RB, Denver Broncos (33.1 percent). The rookie out of Utah has seen a growing workload by the week, and on Monday night he found the end zone for the first time. He's going to remain a part of what Denver does on offense. He's a talented back that should be added by all C.J. Anderson owners and can be grabbed in any league with 12 teams or more for an owner in need of running back depth.

Jack Doyle, TE, Indianapolis Colts (14.9 percent). You have to love the efficiency of Doyle, who has 29 catches on 33 targets so far this season. In his past two games, he has 13 catches on 14 targets for 131 yards and two touchdowns. That has coincided with Dwayne Allen getting hurt (the injury took place early in Week 6). As long as Allen is out, Doyle is a tight end fill-in who has earned the trust of Andrew Luck.

Ka'Deem Carey, RB, Chicago Bears (1.8 percent). Over the past two weeks, Carey has been the best Bears running back, taking work away from Jordan Howard and toting the rock 19 total times. He's a talented pass-catcher as well. I'm not ready to start Carey in my lineup, but he's a player who needs to be added in deeper leagues for the possibility that he eventually usurps Howard for the starting job.

Zach Zenner, RB, Detroit Lions (2.9 percent). The Lions are throwing the ball a ton this year, but with no Dwayne Washington or Theo Riddick in recent weeks, Zenner has taken on a larger role. He found the end zone in Week 7 and seems like the best bet to get the goal-line carries for Detroit until Riddick and Washington return. He's a deeper-league flex play.

Cordarrelle Patterson, WR, Minnesota Vikings (1.1 percent). The career arc for Patterson has been unique, but the former first-round pick has helped Minnesota the past three games. He has picked up 15 catches and a pair of touchdowns in that stretch. Although he's a big play waiting to happen on special teams, Patterson is a short-range target in the passing game. That said, he's already meriting conversation for PPR leagues of 12 teams or larger.

Vernon Davis, TE, Washington (28.4 percent). Without Jordan Reed again in Week 7, Washington relied heavily on Davis. He had six catches for 79 yards and figures to stay involved again in Week 8 if Reed sits. Given his role and the fact that six teams are on a bye in Week 8, he's unquestionably a starting tight end option.

Jamison Crowder, WR, Washington (39.8 percent). This has been a steady season for Crowder so far, with at least nine fantasy points in five of seven games. Again, with Jordan Reed possibly out in Week 8 and DeSean Jackson playing through a shoulder issue, Crowder is a deeper-league PPR add and possible flex play.

Marqise Lee, WR, Jacksonville Jaguars (1.5 percent). Lee, a former second-round pick, has been a consistent part of the Jaguars' offense this season, as he's currently on pace for 101 targets this season. He's worth an add in deeper PPR leagues (14 or 16 teams), even if he isn't a starter at this point. He has flashed intriguing talent this season.

Brandon LaFell, WR, Cincinnati Bengals (12.8 percent). This is an add-and-stash player for me, as LaFell has been very good for Cincinnati the past three weeks (four touchdowns and 14 catches). The mitigating factors: the team's bye is Week 9, and Tyler Eifert will be more involved as each week passes. LaFell is a deeper-league consideration for now.

Chris Thompson, RB, Washington (14.1 percent). My antenna was already up on Thompson, given his contributions in the passing game, but with Matt Jones coughing up the football twice in Week 7, I wonder if Washington might start to incorporate Thompson more as a runner (Robert Kelley could also see more work). Thompson is a deeper-league add and a player to have on the radar if we get indications of Jones' role being altered.
