Fantasy football seasons are won and lost on the waiver wire (Jamaal Charles and Jerome Harrison last year) and 2010 is no exception.
It's already Week 8 and if your team isn't performing, it's time to shake things up.
If you have any dead weight on your team, now is the time to cut it off and pick up some waiver wire gems.
Hart proved he was up to the challenge of starting last week with 12 carries for 84 yards and 3 receptions for 19 yards.
He suffered an ankle injury during the game and could miss a game, but this won't be the last time we hear from the former Wolverine.
Joseph Addai and Donald Brown are injury-prone and haven't been all that effective, and it wouldn't be a shock to see Hart ease his way into the rotation with more performances like this.
It might take a while for this one to pay dividends, but Hart is worth a flier now, before it's too late.
Here's a fun fact: Freeman is the seventh best quarterback in fantasy this year.
Yet he owned is only in 36.2% of leagues.
Freeman has scored double digits in every game except for one, and if he's available in your league, you need to scoop him up.
With Matt Hasselbeck out this week with a concussion, Whitehurst will get the start.
He didn't have a great preseason, but there's a reason that Pete Carroll shelled out a draft pick to get him.
Whitehurst isn't a sure thing, but you don't want to miss out if he goes off this week.
Take a shot on him.
Massaquoi was on most people's watch list before the season, but he has disappointed due to injury.
With the Brown's passing offense showing signs of life under Colt McCoy, someone has to catch passes for Cleveland.
Massaquoi is ready to play after a concussion, and he was just starting to heat up (five rec, 55 yds) before the injury.
Give him a shot.
Tate isn't going to win you any leagues, but he's a great person to have on your bench for a spot start.
He won't get consistent points in the Pats' balanced offense, but he showed he's explosive last week with three rec, 101 yds and a TD.
Tate also should be good for another special teams touchdown this year.
You can get him in almost any league and he has more big-point potential than almost anyone on the waiver wire.
