Not trying to be a homer but I would roll with Jones, only downside is that his value is TD dependent.
I think you are mistaking Cobb for Nelson who will not play. Jennings is back but may still have to get some rapport going with Rodgers, I see Jennings on one side, Cobb mostly in the slot (and really all over the field like Percy Harvin) with Jones running a lot of deep and over routes against a #2 corner at best, most likey a #3.
Jones is probably your home run ball and Steve smith is a bit more of a safer play being a #1 WR in an offense that has been clicking.
Smiths big week last week mostly came in garbage time but there is a possiblity of that happening again, GB vs Det should be a shootout, the first matchup was fairly low scoring and I kinda doubt that happens again.
Thanks for all your help with the Defense Analyzer.
