If the rest of your league is late to the party, make a waiver claim for Detroit Lions running back Mikel Leshoure.
It's not often you can pull a starting running back off the scrap heap at this point in the season, but it was clear in Week Three that Leshoure has replaced Kevin Smith in the Lions' starting lineup.
Leshoure rushed 30 times for 100 yards and a touchdown in the Lions' Week Three loss to Tennessee, while Smith didn't get a carry. Leshoure is on the injury report this week with a groin problem, but it's nothing that will keep him out Sunday against Minnesota.
The Vikings have a formidable run defense, but Leshoure is a good flex play this week, with the potential to be much more than that the rest of the season.
He's not the only potential starting running back who could be available on the waiver wire.
The New York Jets watched Bilal Powell average 4.5 yards per carry last week against Miami, while starter Shonn Greene averaged a meager 2.1 per. Powell finished with 69 yards from scrimmage on just 12 touches. Neither back is a good play against the 49ers this week, but Powell has starting potential going forward.
Atlanta's Jacquizz Rodgers is earning a bigger role in the Falcons' backfield, as well. He's not a threat to take Michael Turner's starting job yet, but Rodgers got 10 carries in Week Three. That alone should put him on the radar in most leagues.
Here are a few other waiver wire options worth considering:
. Christian Ponder, QB, Minnesota: Owned in just 47 percent of ESPN leagues, Ponder is 13th in positional scoring. He has yet to throw an interception and has five touchdowns. You could do worse for a backup QB. He's on the injury report because of a neck problem, but should be fine to play Sunday against Detroit.
. Dennis Pitta, TE, Baltimore: He's got 10 more targets (30) than any of his teammates. Despite that, he's owned in just 62 percent of ESPN leagues. Pitta ranks sixth in positional scoring. He's for real.
. Arizona defense: The Cardinals are second in fantasy scoring, but still available in about a quarter of ESPN leagues. Arizona gets to play Miami, whose best weapon, Reggie Bush, is dealing with a knee injury in Week Four.
. Golden Tate, WR, Seattle: Admit it, you would have been loving that touchdown "catch" Tate had Monday night to beat the Packers if it also gave you a fantasy win. Tate had a pair of TDs against Green Bay, the first multi-touchdown game of his career, and was targeted seven times.
That's good enough to be considered a flex option.
Bye Week is here
Make sure you bench any members of Pittsburgh and Indianapolis, who start the bye season this week.
Up next in Week Five, in case you need to make a waiver wire addition at defense or kicker: Dallas, Detroit, Tampa Bay and Oakland.
Analyzing the Bills
Obviously much is unknown about the Bills' running back situation. If either Fred Jackson or C.J. Spiller is active, they're worth a start. If they're both inactive, Tashard Choice is a good sleeper option.
Receiver Stevie Johnson remains quarterback Ryan Fitzpatrick's favorite target and is finding the end zone. He should remain in your lineup. As for Fitz, his eight touchdown passes are tied for the NFL lead. Sunday's game has shootout potential, so he's a decent sleeper option.
Tight end Scott Chandler ranks 10th in positional scoring, but has just eight receptions on the season. His value is predicated on getting in the end zone. He's risky, but I'd start him this week.
The Patriots are loaded with quality fantasy options: Quarterback Tom Brady, tight end Rob Gronkowski, wide receivers Wes Welker and Brandon Lloyd and running back Stevan Ridley all can be started Sunday.
Stay away from both defenses, though, as the points could pile up fast.
