Fantasy football leagues don't always value wide receivers, but you're going to need depth if your league does.
Calvin Johnson, Larry Fitzgerald and Andre Johnson-type names can only occupy spots on so many rosters. Beyond that, you have your second-tier guys and eventually your bench players.
The waiver wire is in full swing by now, as owners slowly figure out who is going where this NFL season. One key free-agent pickup could prove decisive in a major matchup this season.
Let's take a look at three receivers who are invaluable bench additions entering Week 5.
Jerome Simpson, Minnesota Vikings
Simpson finally returned from suspension against the Detroit Lions in Week 4, giving the Vikings a necessary vertical threat.
He only caught four balls for 50 yards on Sunday, but that doesn't diminish his fantasy value.
According to ESPN, he's owned in less than eight percent of fantasy leagues. That makes him a bargain for anyone who needs more touchdowns from their receiving corps.
Simpson caught 50 balls for 725 yards and four touchdowns for the Cincinnati Bengals last year. He's now a deep threat in an offense otherwise devoid of that type of player.
Look for Christian Ponder to look his way often in the coming weeks. The Vikings are 3-1, and now they have a new toy to play with.
Pick him up, look at the matchup and give him a few spot starts against weak secondaries.
Brian Hartline, Miami Dolphins
Hartline's 12-catch, 253-yard performance was incredible against the Arizona Cardinals on Sunday. Not only should it excite Dolphins fans, but it should make you pick him up in fantasy land.
According to ESPN, Hartline is owned in nearly 29 percent of standard-scoring leagues. Wise owners will have already stashed him on their bench, but don't forget to check.
Ryan Tannehill is getting more comfortable behind center for Miami, meaning their receivers are catching more passes. Hartline took advantage of this in Week 4 with his breakout performance.
Hartline is Tannehill's favorite target. He runs good routes, catches the ball and understands how to play the position. Adding him to your bench is smart, as Tannehill will only improve as the year moves along.
Andre Roberts, Arizona Cardinals
Roberts hauled in six passes for 118 yards and two touchdowns against Miami on Sunday, including this game-tying score with 22 seconds remaining:
Arizona doesn't have a dynamic passing attack, but Roberts is an interesting option in the slot. Larry Fitzgerald receives copious amounts of attention, meaning someone else has to get open underneath.
Roberts proved on Sunday that he can be that guy, and the Cardinals will keep looking for him. He's a speedy option who is slowly finding his niche in the Arizona offense.
According to ESPN, he's owned in less than two percent of their standard-scoring leagues. He's out there, waiting for you to scoop him up.
You're not going to find a ton of upside on the waiver wire at this point, unless you play in some weird four-team league. Guys like Simpson, Hartline and Roberts should be there, and scooping up the hot hand is your best bet.
Grab Roberts and watch him play with an undefeated squad.
