Every week at least one player comes out of nowhere to light it up in the NFL, effectively sending fantasy football owners to "a waiver wire near you."
The trick is to go after the players that make sense and not to simply enter a chaotic state and pick up, say, Golden Tate, the man who boasts after not catching/catching a winning touchdown.
Here's a look at some prime waiver-wire targets as we head into Week 4 of the NFL season.
Arizona's defense has seriously become a force to be reckoned with.
The Cardinals racked up 21 fantasy points in their 27-6 victory over the Philadelphia Eagles in Week 3, posting five sacks and forcing three fumbles along the way (one returned 93 yards for a touchdown by safety James Sanders). Although QB hits don't generally register in fantasy leagues, it is worth noting the Cardinals had 13 QB hits, which means they could have had even more sacks than the five they posted.
This is nothing new this season. The Cardinals have 40 fantasy points through three games, second only to the Chicago Bears.
Despite all of this, they are currently owned in less than 20 percent of ESPN fantasy leagues.
Mikel Leshoure, RB, Detroit Lions
Well, it appears the Lions have found a legitimate threat in the backfield this season.
Second-year running back Mikel Leshoure didn't disappoint in the first start of his NFL career in Week 3 against the Tennessee Titans, blowing up for 100 yards and a touchdown on the ground. This was in addition to him racking up 34 yards through the air.
Remember, after being selected in the second round of the 2011 NFL draft, Leshoure tore his Achilles tendon and was forced to miss his entire rookie season. The fact that he showed this in his first NFL start is very impressive.
Andre Brown, RB, New York Giants
Who is the best RB fantasy option moving forward?
Ahmad Bradshaw is expected to be back on the field in Week 4 against the Philadelphia Eagles, but the Giants certainly won't ignore what Andre Brown did last week against the Carolina Panthers, scorching them for 113 yards and two touchdowns.
The thing is, even if Brown resumes his role as the No. 2 back moving forward, look at what Brandon Jacobs did with the Giants last season in the two-back system. He rushed for 571 yards and seven touchdowns and had 152 carries to Bradshaw's 171.
There is still room for Brown to be a valuable contributor to your fantasy squad even if Bradshaw assumes his No. 1 role again.
