After another exciting Week 1, let's break down which potential fantasy free agents are worth picking up.

Terrance Williams(WR, Cowboys)

He'll be the WR1 in Dallas for at least the next four to six weeks while Dez Bryant is recovering from a Jones Fracture, a very serious foot injury from which others have struggled to come back (such as NBA star Kevin Durant). In most leagues, he should be the top free-agent priority.

Marcus Mariota

(QB, Titans)

It is easy to forget now, but Robert Griffin III (QB, Redskins) helped a lot of people win their fantasy football leagues in his rookie year. Mariota looked similarly dynamic in his debut. He's worth taking a flier on over many safer backup QBs like Joe Flacco (QB, Ravens).

Danny Woodhead

(RB, Chargers)

He is still a key part of the Chargers offense and was being used in red zone opportunities. Even in standard leagues, he should be a good, low-floor bye week fill in.

Chris and David Johnson (RBs, Cardinals)

Chris is probably the better option in the short term while starter Andre Ellington is hurt. However, I wouldn't be too surprised if David Johnson seizes the job before the end of the year.

James Jones

(WR, Packers)

He has retained his fantastic chemistry with QB Aaron Rodgers even after a few years away from home. Don't be surprised if he scores double-digit TDs this year.

Donte Moncrief

@Newsday

(WR, Colts)

He's a fantasy starter with teammate T.Y. Hilton out but that may only be a week or two because Hilton's knee bruise doesn't sound serious.

Tyler Eifert

(TE, Bengals)

If he's still available in your league for some reason, go pick him up right now. He's already worth valuing as a top five TE.

Tyrod Taylor (QB, Bills), Dion Lewis (RB, Patriots), Lance Dunbar (RB, Cowboys), Brandon Coleman (WR, Saints), Tyler Lockett (WR, Seahawks), Tavon Austin (WR, Rams), Darren Fells (TE, Cardinals)
