Week 13 Waiver Wire: Johnny Knox and Others You Must Add

When it's time for fantasy football season to wind down, that means just one thing—playoffs. And with injuries and roster shuffling happening week after week, players that you once counted on to produce for  your team are now falling short of expectations.

The waiver wire is still a great source for talent acquisition, even though its worthy additions have now begun to dwindle. But with a bit of research and patience, you can easily find that missing piece your team needs as the playoffs approach.

Here are four recommended adds as we head into Week 13.

WR Johnny Knox, Chicago Bears (vs. Kansas City Chiefs)

The Chicago Bears offense is now in a state of confusion with backup quarterback Caleb Hanie currently responsible for leading it while starter Jay Cutler recovers from a broken thumb.

He's not doing such a great job of things, if his performance in Week 12 against the Oakland Raiders is any indication.

However, one good thing has come from Hanie's promotion, and it might just benefit your fantasy team.

Bears wide receiver Johnny Knox, who works closely with Hanie on the second-team offense, was targeted at team-high 10 times in Week 12, catching four passes for 145 yards and a touchdown.

Knox has 28 catches for 622 yards and two scores on the year.

With the Kansas City Chiefs coming to town in Week 13, Knox should continue to see a great deal of targets and have the opportunity to make big plays. Keep in mind, of course, that Hanie won't likely throw it 35 times, as he did in Week 12.

It's clear that Knox is going to see a higher number of passes thrown his way with Hanie under center, so if you're in a deeper league or start three wide receivers and have an immediate need, go ahead and take a look at Knox.

WR Harry Douglas, Atlanta Falcons (at Houston Texans)

Though perhaps not a true fantasy starter, for those GMs who want some insurance or depth on their benches, Atlanta Falcons wide receiver Harry Douglas is a great player to stash away.

Douglas caught two passes for 45 yards and a touchdown in his team's Week 12 win over the Minnesota Vikings on Sunday.

Fellow receiver Julio Jones was in and out of the game, though perhaps not because of the hamstring injuries that have been bothering him all season long.

This means that Douglas still has fantasy value any time Jones hits a rough patch.

If you own Jones and are headed into the playoffs, I recommend grabbing Douglas as a backup plan.

RB Maurice Morris, Detroit Lions (at New Orleans Saints)

For fantasy GMs who picked up Detroit Lions running back Maurice Morris in recent weeks only to find out they grabbed the wrong Lions rusher, they now have a bit of value on their hands.

Recently-signed back Kevin Smith left Thursday's game against the Green Bay Packers with what is being called an ankle sprain, and Morris took over his duties.

Morris did a good job, though he's clearly not one of the most dynamic backs in the league. He rushed seven times for 39 yards and caught nine passes for 81 more, and he has 55 rushes for 240 yards and a score and 19 receptions for 170 yards on the season.

Should Smith not play in Week 13 against the New Orleans Saints, Morris has value as a one-week starter, especially in PPR leagues.

TE Jermaine Gresham, Cincinnati Bengals (at Pittsburgh Steelers)

Though Cincinnati Bengals tight end Jermaine Gresham has had quite the breakout year, he's still owned in just 38 percent of Yahoo! fantasy leagues.

Outside of the very top performing tight ends, the position one of the most unstable this season.

If you are unsatisfied with your fantasy tight end, adding Gresham to your lineup may be your best move. Gresham had five catches for 68 yards and a touchdown in the Bengals' Week 12 win over the Cleveland Browns, and he has 37 catches for 370 yards and five scores on the year.

And if you're satisfied with your tight end, you can still grab and add Gresham if you need someone to plug into the flex position.

Though the Pittsburgh Steelers and their talented pass defense are ahead, that may mean a big day for Gresham as their defenders focus on receivers A.J. Green and Jerome Simpson.
