As the Fantasy Football season continues, the waiver wire becomes even more important. Injuries leave owners with questionable players in their starting spots, and bye weeks make it even harder to field a quality team each week. That's why it's important to continue to build your fantasy team throughout the season. To do that, fantasy owners should be making moves on the Waiver Wire every week. Let's take a look at which players need to be targeted on the waiver wire in week 5.

1. RB Alvin Kamara (17.5% Ownership)

The Saints have finally committed to a running back, and his name isn't Adrian Peterson. In London, Kamara had a whopping 10 catches for 71 yards and a touchdown.

He also added 25 yards on five carries on the ground, for a total of 15 fantasy points. New Orleans clearly wants to get Kamara the ball, and his ability as a receiver makes him a noteworthy fantasy player. Grab him from the waiver wire if he's available in your league.

2. WR Will Fuller (5.9% Ownership)

In his first game back, Fuller had a great day, catching two touchdown passes and scoring 15 fantasy points. Deshaun Watson looks like a Pro Bowler right now and the Texans offense has woken up. That makes Fuller, who will likely be the secondary wide receiver target in Houston's offense, worth a speculative add from the waiver wire.

3. RB Wayne Gallman (0.2% Ownership)

It only took the Giants three games to figure out that Gallman, who averaged about four yards a carry in week 4, is the best running back on the roster.

He had 42 rushing yards and also scored a touchdown in the passing game, giving him a total of 10 fantasy points on the day. Gallman should now be tabbed as the starter in New York, which means he should be plucked from the waiver wire in most fantasy leagues.

4. WR Devin Funchess (10.8% Ownership)

There's more than one wide receiver in Carolina, and Funchess proved it against the Patriots. He caught seven passes for 70 yards and two touchdowns, scoring 19 fantasy points. If Cam Newton can continue to play like he did against the Patriots, Funchess could easily become a flex player each week.

5. QB DeShaun Watson (22.1% Ownership)

It's time to give credit to rookie DeShaun Watson, who led the Texans to a whopping 57 points against the Titans this week. Watson had a whopping four touchdown passes and ran for another one. His ability to run makes him a dangerous fantasy threat, and it's starting to look like Watson might finish the year as a top 10 fantasy quarterback.

6. RB Wendell Smallwood (14.4% Ownership)

Smallwood should have been owned in most fantasy leagues after last week, but he wasn't really picked up. In week 4, he scored 10 fantasy points and had a rushing touchdown. Blount had a great day too, rushing for more than 100 yards, but without Darren Sproles, there are enough touches for each to be fantasy relevant. And if Blount did get injured, Smallwood would immediately become a top 10 fantasy running back.
