Seven weeks down, six to go. It's kind of sad that we're already past the halfway point of the Fantasy season, but we're also that much closer to earning playoff spots, clinching title game matchups and winning some leagues.

Now's the time to take inventory of rosters and figure out just how close you are to a Fantasy title. If you're 7 -0, 6-1 or 5-2, you're looking pretty good. If you're 4-3 or 3-4 you're not bad at all -- you just need to win. If you're 2-5 or worse you're on thin ice. No matter what, now's the time to make a move. And I'm not talking about dancing -- I'm taking about making a trade.

In order to get something you need, you need to give up something someone else wants. So your first move is to identify the players on your roster than people might want. Then, match up those players with the needs of other owners. It does you no good to offer someone Golden Tate if they already start Demaryius Thomas and Antonio Brown, but the guy who has been scraping by with Larry Fitzgerald and Roddy White might be interested.

The problem is that most of the time owners want the very best players. To get those guys, you'll either need to give a very good player in exchange or deal off two starter-quality guys for one stud. Those are the two kinds of deals you'll see play out in most leagues with some two-for-three and even some three-for-three swaps mixed in. But it's those owners with excellent depth who can consolidate it into an elite-level player.

Fantasy owners aren't just looking for deals -- they're looking for steals. They're also looking to dump players who are hot right now but could turn cold in a week or two. That's the focus this week -- if you can't afford a top-shelf starter, aim for one of these buy-low suggestions, perhaps by dealing off a sell-high guy.

Buy low

Tre Mason, RB, Rams: Chances are someone in every league is going to pick up Mason off waivers this week. If it's not you, swoop in and make an offer. Jeff Fisher-led teams have shown a commitment to their best backs through the years and Mason figures to be the best guy for the job in St. Louis. Besides, who can resist trading away a player they literally just picked up off waivers for a starter? The clock's ticking on getting him for cheap.

Jerick McKinnon, RB, Vikings: There was never any question about McKinnon's raw talent, but now that he's been picking up the nuances of the pro game, he's quickly morphing into a legitimate starting Fantasy back. The touches and playing time over the last two games are all you need to see to recognize McKinnon as the Vikings' top back, for better or worse, for the rest of the season. Before Week 7, no team's group of running backs had totaled 100 yards against the Bills. McKinnon exceeded that.

Darren McFadden, RB, Raiders: I can't believe I'm saying it, but McFadden is a good player to trade for in that he'll come cheap and has the role of starter on lock down. We're headed into Week 8 and he doesn't have a tear or a pull or a break or anything. It could happen in a few weeks, but that's why his price tag shouldn't be too high. If you're in a real pinch at running back this could be the stopgap you need until someone shakes out on waivers.

Matthew Stafford, QB, Lions: When Calvin Johnson comes back, Stafford's numbers should pop. Teams who have Stafford and another quality quarterback should be receptive to dumping him for whatever they can get. After their bye (when Johnson is expected back), the Lions face only three teams currently ranked in the Top 12 in Fantasy points allowed to quarterbacks including the Vikings, who are only in the Top 10 after how they started the season, and the Packers, who they take on at Lambeau in Week 17.

Calvin Johnson, WR, Lions: See above. Desperate owners with a losing record will pawn Johnson for two good starters.

Sell high

Terrance Williams, WR, Cowboys: On the season, Williams has 338 yards and six touchdowns on just 19 catches over 31 targets. That's effectively 18 yards per catch, a touchdown every three catches and a touchdown every five targets. Call me skeptical, but I don't think he keeps it up. When he gets targets his numbers are good -- in three games with six or more targets he's delivered at least 11 Fantasy points. But in the four games with three targets or fewer, he's had nine Fantasy points once and seven or less three times. Naturally, the targets seem to come when Dallas plays from behind or in a competitive game. Looking at their rest-of-season schedule, the Cowboys appear to have some games left where Tony Romo will need to throw -- maybe that means something good for Williams, but I'd rather turn him into a running back like Justin Forsett or Ben Tate.

Lamar Miller, RB, Dolphins: If you can cash in on an owner buying into the allure of an every-down back, Miller will bring you back quite a bit in trade. The only reason to consider trading Miller is because of his upcoming schedule, which includes five games against defenses in the Top 10 in Fantasy points allowed to running backs, and that doesn't include trips to Denver or New England. Don't give Miller away for peanuts, but if someone is willing to overpay, let them ... after his Week 8 game at Jacksonville.

Mike Wallace, WR, Dolphins: Wallace has the same schedule as Miller and faces his own share of tough pass defenses after this week's game. He's been very touchdown dependent and doesn't have more than 81 yards in a game this season. He also doesn't have more than 12 Fantasy points in a game yet this season.

Jay Cutler, QB, Bears: It'll take more than one bad game from Cutler for his Fantasy stock to sink, but a tough schedule coming up doesn't help him, nor does an offensive line that's taking longer to heal up than first believed. Plus, Cutler has a pretty clear track record of getting banged up -- are we sure he'll take every snap for the Bears? I wouldn't deal Cutler if you don't have an alternative to start, but if you do then seek out the owner who has Matt Ryan and see if he wants to make his team better. Heck, you could even consider a Cutler-for- Stafford deal
