Simple: I drafted the wrong guys.
I started off w/ a bang by taking Ray Rice instead of Shady. I then doubled-down by taking Dez, buying the hype that he'd be the clear #2 fantasy WR behind Megatron, maybe even have a shot at displacing him for #1. Then once Stafford was taken, I took Romo, who hasn't been awful by any means, but he's been very mediocre since the week 5 Denver game.
Gracon has gotten a ton of targets, but not enough TDs, and not enough YPR to really be impactful; another guy who hasn't been terrible by any stretch, but still, not big time production either.
Lacy was a godsend, but then Rodgers gets hurt. Oh, and I picked up Keenan Allen a week before he was really on the radar, so that was a positive move, as was a week 7 trade that included me moving Ray Rice, getting Gronk in return. Let's see, what else? Vernon Davis has had some big games (TE is not mandatory in this league, but we have 2 FLEX), but I haven't been starting him lately (going Gronk/Allen @ FLEX).
Ridley's ball security issues caused me to miss out on his nice little run prior to the Denver game benching. Now he's totally, utterly useless.
I've gotten ONE good DST performance (when Cincy torched the Jets). Other than that? Pretty much nada.
Thus endeth the story of my season.
