Coming into the season, probably the hottest name among QB sleepers was the Falcons' Matt Ryan. After flashing signs of stardom as a rookie, it looked like added experience and Atlanta's addition of TE Tony Gonzalez would be exactly what he needed to make a huge leap in Year Two. But at least from a fantasy standpoint, he's surprisingly remained just an average quarterback.

At the midway point of 2009, Ryan ranks 15th among QBs in fantasy points, meaning he hasn't been starting caliber in most leagues. And while it might not seem like he's played all that poorly, he's only averaging about a half-point more than a guy like Chiefs QB Matt Cassel, who certainly hasn't stood out thus far. The numbers he's on pace for — 3,568 yards and 26 TDs — definitely aren't bad, but when you factor in that he's on track to toss 20 INTs, it brings down his fantasy value a fair amount.

So, why exactly has Ryan struggled? While no reasons instantly jump out, it's clear that his downturn began in Week Six. After throwing seven TDs and two INTs in his first four games, he has tossed six TDs and eight picks in his last four outings. He's also averaged just 202 passing yards during that four-game stretch. Basically, it's been a tale of two halves for the Atlanta QB.
