Fantasy Football: Big producers — Kareem Hunt — can become mortal fast

The winds of change are blowing . . . and fantasy fortunes are rising and falling in turn.

Just a month ago, it seemed that those of us without a heavy investment in the Chiefs’ offense were destined to play for second place. Alex Smith was the top fantasy passer in the land. Kareem Hunt was on his way to shattering every rookie record in the books. And Tyreek Hill was scoring at will.

Not so much anymore. Smith has reverted to his pedestrian ways, Hunt hasn’t sniffed the end zone since Week  3, and Hill’s “SportsCenter” moments have been coming with less frequency.

Only Travis Kelce has held up his end of the bargain. But that has long been the case.

Of course, the Chiefs aren’t the only ones to abandon their fantasy owners as the stakes get higher.

Remember when Jordy Nelson was a thing? I realize Aaron Rodgers has left the building, but somehow Davante Adams is prospering in the Brett Hundley era for the Packers. Wherefore art thou, Jordy?

The Cowboys’ offense is imploding without Ezekiel Elliott and Tyron Smith, while the incredible shrinking Dez Bryant seems incapable of helping Dak Prescott keep the wheels from flying off.

The Vikings’ Case Keenum has turned Adam Thielen into a fantasy stud while Stefon Diggs watches longingly from the shadows.

And will the real Raiders please step forward? Actually, will the 2016 Raiders please return?

Catch ’em while you can

Samaje Perine, RB, Redskins. Perine took advantage of his starting opportunity, rushing for 117 yards and a TD in Sunday’s tough matchup with the Saints. And now that Chris Thompson has joined Rob Kelley on the sidelines for the rest of the season, Perine’s value is magnified. Look for more passes thrown his way, too.

Austin Ekeler, RB, Chargers. This is the point when backup kickers and defenses should be ejected and skill-position depth added. Ekeler has put up impressive numbers in recent weeks, and Melvin Gordon’s owners are foolish if they don’t handcuff him heading into the stretch run.

Dede Westbrook, WR, Jaguars. The ultra-confident rookie wideout fell well short of the ridiculous 200-receiving-yards proclamation he made before his NFL debut, but he still deserves consideration. He should be fully integrated into the passing game over the next couple of weeks, and he could be a valuable contributor during the fantasy postseason.

Kenny Stills, WR, Dolphins. Stills is available in most leagues because he’s the third receiver in a pass-challenged offense. Though inconsistent, he showcased his playmaking skills against the Bucs on Sunday and has far outperformed the more heralded yet underachieving DeVante Parker.

Greg Olsen, TE, Panthers. Olsen is eligible to return after the bye from the broken foot he sustained in Week 2. With Kelvin Benjamin now in Buffalo, Olsen should instantly rekindle his bromance with Cam Newton.

Don’t be fooled

Damien Williams, RB, Dolphins. Williams’ big game was more a reflection on the dicey proposition any Dolphins back represents rather than a sign of things to come. Take away his 69-yard burst Sunday, and the rest of his carries were meaningless. Neither he nor Kenyan Drake will carry you to a fantasy title.

Ricky Seals-Jones, TE, Cardinals. There’s a reason Seals-Jones isn’t owned in any league on the planet: He’s a third-string tight end, and his three receptions Sunday were the first three of his career. The undrafted former Aggie should be nowhere near any fantasy roster.
