In fantasy football, nothing can ruin a season faster than watching in horror as your first-round running back goes down in a heap in Week 3.
That's it. Season's over, right?
Maybe not, if you purchased insurance against injury by "handcuffing" your star tailback with his backup.
On some NFL teams, the backfield situation is just too muddied for there to even be a handcuff. It's a committee, and the only way that having both backs will pay big dividends is if one goes down with an injury.
Think Giovani Bernard and BenJarvus Green-Ellis in Cincinnati, or DeAngelo Williams and Jonathan Stewart in Carolina.
There are also situations where locking up both halves of a tandem backfield can be a very expensive proposition, such as with David Wilson and Andre Brown of the New York Giants.
This isn't to say that having both backs in such a situation is a bad idea. Any player is worth drafting at the right price.
However, the better handcuff situations fall into one of two categories.
First, there are the clear backups who can be had very late in drafts. These players have little value other than as handcuffs, making it easier to acquire them without breaking the bank.
If you have to spend big on a backup, you want one with big-time upside, a player who has already shown he's capable of carrying the load.
It's those types of situations we'll examine here, with a look at the top fantasy handcuffs of 2013.
