No matter where your fantasy football teams are sitting in the rankings, it's never too late to improve.

You can study the waiver wire and make the right start-or-sit choices, but the trade market could be the route you need to take.

In a game full of uncertainty, one thing is certain: it's never time to get complacent with your fantasy football teams. You work the waiver wire hard, and you ponder start-sit questions all week. You should be just as active in the trade market.

That can be tricky, of course, as not every fantasy player values the same football player the same way. Plus, sending an insultingly low-ball deal to initiate the back-and-forth is never a good idea. (Seriously, don't do that.)

To help, we'll be offering up our updated trade values to help you figure out whether or not you should send or accept a trade.

Keep in mind that these are entirely based on rest-of-season projections rather than gut feel or upside. Players with defined roles, frankly, can have more value than players we simply hope break out if things go their way. The algorithms are here to remind us of that.

Teams that served their byes will naturally get a boost in rest-of-season value. That'll explain why some players are a few spots higher or lower than anticipated.

Also, keep in mind: these aren't my rankings or values. They're math-based values to help us make optimal decisions stemming from what is most likely to occur.

With all that said, here is how numberFire's algorithms value players for the rest of the season in a 12-team league.
