Each year, fantasy football owners miss out on lesser-known offensive weapons who have flown under the radar, either due to an abundance of other talented players around them or simply being members of struggling teams.
The 2013 NFL campaign has been no different, as are a number of rather unheralded players who appear to be worthwhile fantasy additions after three weeks of what has undoubtedly been an unpredictable start to the season.
With that in mind, here's a look at the most valuable waiver wire pickups going into Week 4 of the 2013 fantasy football season.
Prior to the beginning of the Dolphins' season, it was widely assumed that Mike Wallace would be the team's undisputed No. 1 receiver.
But so far, the former Pro Bowl wideout has been maddeningly inconsistent, and quarterback Ryan Tannehill has been forced to look elsewhere to rack up yardage.
Well, Tannehill's picked up right where he left off last season with former Ohio State standout Brian Hartline, as the 26-year-old has a very impressive 238 yards through the first three weeks of Miami's schedule.
Yes, a good chunk of those yards came during the Dolphins' Week 1 triumph over the Browns, when Hartline racked up nine catches for 114 yards.
However, Hartline has remained productive since then, as the former fourth-rounder has averaged over 60 yards a game in his two subsequent outings, so it's a wonder that he's owned in less than 45 percent of ESPN fantasy leagues.
Soon, the secret will be out on the Canton, Ohio native, so be sure to grab him before someone else does, because if his early production is any indication, he's a lock to record his second consecutive 1,000-yard season.
After putting up 1,007 yards as a rookie in 2010, LeGarrette Blount seemingly disappeared and has failed to come anywhere close to matching the first-year totals he recorded with Tampa Bay.
But now, as a member of the Patriots, Blount finally looks like he's found a new home in the NFL, as he's become a valued member of New England's pass-happy offense.
After being used sparingly during the Patriots' first two games, Blount finally got a chance to prove himself during Week 3 against his former team, the Bucs, and he was much better than expected.
With 65 yards on 14 carries, Blount demonstrated that he's capable of being Bill Belichick's featured back, as those totals represented an improvement from former No. 1 rusher Steven Ridley's season-high of 46 yards on nine carries.
Though it's still a bit early, if you have space on your roster, Blount is worth a look, because as he showed last weekend, he still has the skill and talent to be an impact player in the NFL.
Over the course of his decorated career with the Patriots, Tom Brady has consistently made fantasy stars out of previously unknown offensive weapons. At least for the time being, Aaron Dobson appears to be a prime candidate to be the next one.
Sure, Julian Edelman has garnered more headlines after his two-touchdown outing in Week 1, but Dobson, a 2013 second-rounder merits consideration as well, especially after his Week 3 performance against Tampa Bay.
Until Rob Gronkowski and Danny Amendola are back in the lineup for New England, Dobson will likely continue to be a favored target of Brady's, which means unless he's dropping passes, he'll be putting up decent numbers at the very least.
Against the Buccaneers, Dobson registered a respectable 52 yards on seven catches, which isn't even his most productive game on the year to date, as he caught three passes (but was targeted on another seven) to finish with 56 yards against the Jets.
As someone who is owned by less than eight percent of fantasy owners in ESPN leagues, Dobson is worth a look, because as Brady's shown us constantly, he's capable of turning average receivers into stars with relative ease.
