Fantasy football trade index and rest-of-season rankings: Time to trade for Matthew Stafford?

One week of the NFL season is complete and fantasy football managers are ready to overreact! Hey, it comes with the proverbial territory to look extra close at the Week 1 numbers because that is all we have, then totally adjust all the preseason expectations. In most cases, of course, this is silly. OK, so Green Bay Packers quarterback Aaron Rodgers played poorly. Marcus Mariota and two other backup quarterbacks outscored him. It happens. It is one week.

We are trying something new in our rest-of-season rankings column, combining the ample lists with a trade index by position, one analyst's thoughts on players whose value actually might have adjusted. Trading is never a sure thing in any fantasy pursuit, as it takes more than one manager to, well, tango, but now is absolutely the right time to trade for Rodgers. In fact, it might be the last time to do so reasonably. So here we go and enjoy the rankings!

Quarterback

Rankings changes: Little adjustment among the QB1 options, though Philadelphia's Jalen Hurts sure looked impressive and moves up a few spots. ... Josh Allen versus Kyler Murray for the No. 2 QB spot sure is intriguing, but no change yet. ... Chicago's Andy Dalton looked so special that his backup Justin Fields moves up into QB2 range. ... Atlanta's Matt Ryan did not play well. Is he still a QB2? ... The Giants' Daniel Jones fumbled while you read this. Is he even a QB3? ... Washington has a new starter, if you care.

Trade for: Rodgers, obviously. Do not read into one awful outing unless it happens again this Monday against the bad Detroit Lions. Watch Rodgers drop four touchdowns on them. ... Former Lion Matthew Stafford is going to force his way into the top 10 real soon. ... Two more weeks before Fields is starting? Do not wait that long to deal for him. ... Patriot Mac Jones might be more valuable in fantasy this season than Trevor Lawrence, thanks to what is around him, coaching, etc. No, really.

Be cautious trading for: Jameis Winston, obviously, is not likely to ever throw five touchdown passes with only 148 passing yards again. Why? Well, it never happened in NFL history before! Perhaps this is a new, efficient Winston, but we need to see more. ... New Lion Jared Goff might be trailing by multiple touchdowns each week and padding his numbers that way, but it is dangerous to assume it. ... Some might buy low on Jacksonville's Lawrence, but he might not play a weaker defense than the Texans the rest of the way, and that was not a great performance.

Running back

Rankings changes: Again, trust the RB1 options for a lot longer than one week. The Bengals' Joe Mixon did push his way into the top 10, though. The Giants' Saquon Barkley leaves the top 10, though really, we expected a tepid workload in September, so perhaps this is unfair. ... San Francisco 49ers rookie Elijah Mitchell is the coveted free agent signing and new starter, though he falls a bit short of RB2 status for now. The 49ers like to share the running back wealth. Raheem Mostert barely remains in the top 200, though we might not see him again until November. If you want to move on, do so with no regrets. ... Youngsters Kenneth Gainwell, Larry Rountree III and Tony Jones Jr. are knocking on that top 100 door and worth our attention.

Trade for: Barkley might need a few weeks to emerge as a fantasy savior, but looking at what is around him, it might be tough for him to deliver his rookie numbers again. Assume he is a RB2 choice, and trade for that accordingly. ... Not certain I would trade for Jacksonville's James Robinson as if he will duplicate his rookie stats, though it seems unlikely his lowly Week 1 volume is the new norm. Robinson should be a safe flex option. ... Aaron Jones is still good. He should run well on the Lions. ... Melvin Gordon III had the big run of Denver's opening day, but Javonte Williams remains the future.

Be cautious trading for: Detroit's Jamaal Williams scored his touchdown very late, and D'Andre Swift has to be the future there. But you knew that. Also, 20 targets between them, whoa. ... Neither Josh Jacobs nor Kenyan Drake ran particularly well on the Ravens, but it is easy to see a timeshare here, and that is bad for Jacobs' value. ... The Rams' Darrell Henderson Jr. looked strong, but we do not suddenly disregard his brittle label because he stayed healthy for one contest. ... Ignore the Buffalo Bills running backs. This is a recording.

Wide receiver

Rankings changes: San Francisco's Deebo Samuel saw major targets and Brandon Aiyuk did not, altering the hierarchy here. Samuel moves up. ... Rookies DeVonta Smith and Ja'Marr Chase looked terrific and rise into strong WR3 territory, previously noted in this column. ... New Jet Corey Davis has yo-yoed with the feelings of fantasy managers before, but he sure looked good on Sunday. ... Injuries to Denver's Jerry Jeudy and Washington's Curtis Samuel send them dropping in the rankings and off rosters.

Trade for: Green Bay's Davante Adams will be fine, of course, though Tyreek Hill does pass him in the rankings. ... Atlanta's Calvin Ridley will also be fine. ... The Rams' Robert Woods saw a mere four targets, as Cooper Kupp rocked, but each will be WR2 options. ... Tom Brady boasts three productive wide receivers, so even though Mike Evans was quiet in Week 1, he will have plenty of excellent fantasy games.

Be cautious trading for: It is easy to be a Mike Williams (Chargers) fan, but let us remember he still has not eclipsed 50 catches in any season. ... New Titan Julio Jones is better than his 29 receiving yards and 4.8 yards per target, but assuming he plays enough to reach 1,000 yards remains the concern. ... If you really want the Giants' Sterling Shepard, be our guest. Trade the farm for him. Kenny Golladay did not look like a WR2, either.

Tight end

Rankings changes: Not much, though the Raiders' Darren Waller seeing 19 targets is mind-blowing. He slips past George Kittle into the No. 2 TE spot, for now. ... The Saints' Juwan Johnson caught a few touchdowns, but he still misses the top 20, again just for now. ... Eight targets for new Charger Jared Cook is a reminder he always seems to matter, wherever he plays.

Trade for: Atlanta rookie Kyle Pitts might become available in your league after doing little in Week 1, but he will still be as awesome as everyone thought.

Be cautious trading for: Rob Gronkowski loves the spotlight and the big games, but whether he gets as excited to face Atlanta and the Jets is another matter. Gronk had eight targets and two scores. He averaged fewer than five targets per game last season.
