Fantasy Football Week 5 Rankings: Mark Sanchez and 3 Worst QBs

Throwing the football at a high level of consistency is quickly becoming the norm in pro football.

Therefore, it's only making QBs that much more valuable in fantasy football.

However, not all of the QBs have caught up yet to playing well all the time.

You can easily tell the difference between the great ones from the rest of the bunch, because their numbers are always solid and even when they're nor up to par within themselves, they're still better than the good or average QBs.

So with that, here are the Top 3 worst QBs for Week 5 in fantasy football.

3. Mark Sanchez, Jets (at Patriots)

Unless it's the postseason, we need not worry about Mark Sanchez playing well on a consistent basis.

Which in turn, causes an issue for his fantasy owners since everyone needs a backup, because he's clearly not a starter.

And this week there won't be anything we haven't seen from Sanchez in the regular season, as he's thrown six TDs to five picks and a 55.1 completion percentage through four games, but saw his QB rating drop from 93.8 in Week 3 to 30.5 in Week 4.

Bill Belichick's defense has been gradually improving with every week, and you can guarantee he'll have his dark-side focused to shut-down Sanchez.

2. Matt Cassel, Chiefs (at Colts)

Last season it was okay that Matt Cassel wasn't performing at a high level each week because RB Jamaal Charles was having a great year.

This season though, Cassel has performed about the same but without a running game, K.C. is lucky to even have one win.

This week against the Colts, Cassel better learn to scramble quickly because the Colts' defensive line is bringing the pain with every snap like they've done each of the past two weeks.

Now include their non-existent rushing attack and the Cassel will be under pressure all day.

In 2010 he was as decent starting option in fantasy, in 2011 however, he is not even a solid backup.

1. Jay Cutler, Bears (at Lions)

Until Jay Cutler can figure out how to throw the ball in the west coast offense, RB Matt Forte is going to run the rock virtually every down.

That being said, Cutler also has trouble playing well in road games, as evidence by his 19-of-45 performance at New Orleans in Week 2.

He went from a QB rating of 107.2 in Week 1 to 67.3 in a span of one week.

For a player who's expected to learn from one of the best offensive coordinators in the NFL (Mike Martz), Cutler is clearly not learning fast enough to keep pace.

And if that continues, say good-bye to the postseason if you play him in fantasy, and if you're a Bears' fan, also say good-bye to the postseason.
