Fantasy football leagues arent won during the first few rounds of your draft. Much to our chagrin, guys underwhelm and/or go down with injuries. For this reason, its important to become familiar not only with superstars but also with role players and emerging youngsters who could find themselves on the fantasy radar during the 2016 season.Last year, the likes of John Brown, Kamar Aiken, Ted Ginn Jr., Donte Moncrief, Rishard Matthews, Stefon Diggs, Willie Snead, James Jones and Tyler Lockett entered the season third or lower on their respective teams depth chart. It didnt take long for each to land in the fantasy spotlight, though.With that in mind, I have ranked the current No. 3 wide receivers for each NFL team in terms of expected 2016 fantasy production -- not strictly on skill. As youll see in the explanations, scheme, playing-time security and supporting cast are among the other variables in play.Some of these players are worth your attention on draft day, while others are names to scoop up in dynasty leagues or to file away for later.1. Michael Floyd, Arizona CardinalsWhy Floyd and not Brown? Floyd averaged 42.6 snaps per game last season, compared to 52.2 for Brown. Of course, even if we flip-flop the two, Brown would be ranked first in this list. Arizona was in the middle of the pack in three-wide sets but had a fourth wide receiver on the field on 23 percent of pass plays last year, which was second-highest in the league. Put another way, Cardinals coaches found reps for J.J. Nelson without impacting the snap counts of Brown, Floyd and Larry Fitzgerald. Arizonas pass-first, high-scoring offense can support three receivers, which supplies Floyd with WR2 upside.2. Michael Thomas, New Orleans SaintsThomas may eventually move past Snead in terms of target priority, but hell start out third in line at the position. A rookie, Thomas?is ticketed for Marques Colstons big slot role, which should generate plenty of volume, and his 6-foot-3 frame is sure to lead to a lot of work near the goal line. Theres been some speculation that Brandon Coleman could push for this job, but thats hard to believe after he quickly lost his job to Snead last season. On the negative side for Thomas, New Orleans has ranked no higher than 19th in the league in three-wide sets when passing over the past five years. Still, the presence of Drew Brees and a fairly clear path to targets put Thomas squarely in the flex discussion.3. Phillip Dorsett, Indianapolis ColtsAndre Johnson is no longer in the picture, which locks Dorsett in as the clubs No. 3 receiver behind T.Y. Hilton and Moncrief. Having relied heavily on Coby Fleener and Dwayne Allen, the Colts havent used a ton of three-wide sets during the Andrew Luck era, but they were in the upper half of the league last season and Fleener is now out of the mix. Common sense (not to mention the insight of Colts analyst Mike Wells) suggests Dorsett -- a 2015 first-round pick -- will be on the field over tight ends Jack Doyle or Erik Swoope when the team is passing. Considering the Colts pass-heavy, high-scoring attack, its not inconceivable that Dorsett will flirt with WR3 numbers as the teams third option in the passing game.4. Kamar Aiken, Baltimore RavensThe Ravens wide receiver depth chart is a bit tricky to sort out. Steve Smith Sr. will return as Joe Flaccos top target, but after that, newcomer Mike Wallace, 2015 breakout player Aiken and 2015 first-round pick Breshad Perriman?are battling for snaps. Baltimore had its third wide receiver on the field for 62 percent of its pass plays last year, which ranked 27th. The added receiver depth might seem to suggest that number will rise in 2016, but thats not necessarily going to be the case after the Ravens added tight end Benjamin Watson to a unit that also includes Maxx Williams, Crockett Gillmore and Dennis Pitta. Aikens playing time is a question mark, but he could very well lead this team in targets. Hes worth targeting in the mid-to-late stages of your draft.5. Jaelen Strong, Houston TexansStrong is generating a lot of offseason hype, and its very possible that hell end up second on the depth chart in Houston. Im still giving a slight edge to Will Fuller, who was selected in the first round of Aprils draft and is coming off the board earlier than Strong in summer fantasy drafts. Strong, a third-round selection in 2015, will compete with Fuller, Cecil Shorts III and Braxton Miller for reps. Although Houston relies heavily on its defense and running game, the offense ranked 11th?in three-wide sets and was one of only three teams with a fourth receiver on the field more than 10 percent of the time when passing last year. Strong is an intriguing post-hype sleeper, but hes still a raw 22-year-old with an unproven quarterback in Brock Osweiler. Strong has enough breakout potential to warrant a late-round flier.6. Sammie Coates, Pittsburgh SteelersMartavis Bryants season-long suspension leaves Coates positioned to work as the Steelers No. 3 receiver this season. The 2015 third-round pick will compete with Darrius Heyward-Bey and slot man Eli R
