If you want to win your fantasy football league, you need to scour the waiver wire at every opportunity.
Rarely can you rely on just the players you drafted to get you through a season. Guys get hurt or underperform, leaving you no choice but to look elsewhere for alternatives. Also, there are the players no one drafts that go on to be fantasy studs.
You've got to get the jump on the competition when it comes to the waiver wire.
These four players aren't going to win your league, but the points they give you could be enough to make the difference between a win and a loss in your Week 4 matchup.
Alex Smith, QB, Kansas City Chiefs
Alex Smith isn't a prolific quarterback and should be nothing more than a spot starter in almost every league. He doesn't make big plays in the Kansas City Chiefs offense, and Jamaal Charles is there to carry much of the offensive burden.
If you're looking for a steady backup, Smith is your guy. His floor is not all that low, and he's capable of having at least one huge performance per season.
For the owners that have to sit Aaron Rodgers or Cam Newton this week, Smith is a solid option to start. He's going up against a spotty New York Giants defense that's just good enough against the run that it could force the Chiefs to open up the defense a little more.
Jason Snelling, RB, Atlanta Falcons
Steven Jackson is going to be out until Week 7 (h/t ESPN.com's Vaughn McClure via Adam Schefter).
That means Jacquizz Rodgers and Jason Snelling will continue splitting time in the backfield for the foreseeable future. Rodgers is the better pickup, so if you can snag him, do it.
The problem is, everybody knows Rodgers is going to get more carries. He's probably been snapped up in most leagues.
Snelling is a more than adequate addition, though. He's the bigger back, so he'll get more opportunities in the red zone. Plus, Snelling is a threat in the passing game. Last week, he had four receptions for 58 yards and a touchdown.
Kenbrell Thompkins, WR, New England Patriots
It's a bit surprising that Kenbrell Thompkins is available in 40 percent of leagues on Yahoo! and a little less than 65 percent of leagues on ESPN. The rookie wideout hasn't been a huge hit through the first three weeks, but you'd think more people would've snapped him out by now.
Until Rob Gronkowski and Danny Amendola get healthy, Thompkins should occupy a place on your fantasy roster. He's got the potential to have a performance like he did on Sunday, with two touchdowns and 41 yards receiving.
Thompkins should improve as the season goes on as well. Tom Brady is going to trust him more and more in the passing game, and that's just going to mean more targets.
Charles Clay, TE, Miami Dolphins
Fantasy tight ends are always so hard to predict. You draft the established guys high, only to have somebody like Jordan Cameron or Julius Thomas explode in Week 1.
By now, most of the best options have already been snapped up. If you're looking for a high-risk, high-reward option, look no further than Charles Clay.
He's been targeted quite a bit by Ryan Tannehill through the first three weeks, getting 14 receptions and 203 yards. The lack of touchdowns are a bit of a concern, but you wouldn't expect that to be the case for much longer.
Clay also offers a rushing threat in the red zone. The Miami Dolphins aren't afraid to give him the ball close to the goal line, and Clay had a touchdown run in Week 2.
