Detroit has a great schedule, in large part due to the NFC north and playing the Vikes twice. I think he'll be a good option. They'll probably be losing most of time and have to throw. The D's the face aren't that good, so he should be pretty productive. I'd rate him ahead of Andre Johnson. With Mooch running the show, and what looks like a better QB in Harrington and an easy schedule, it's hard to hate on him too bad if you grab him late or get him cheap in an auction.
$8/$100 sounds spendy for a rookie WR, but I don't do auctions, so I'm pretty clueless about what his value is.
