I think it will be exactly like you said. They will have a handful of plays for him &, if he breaks one for a touchdown like last night, then he will be a good play. WAY too many weapons right now in Green Bay &, with Cobb only getting maybe 5-6 looks per game, that is not enough to trust him yet. The kick returns make it a little more interesting, but not enough to bite.
Another WR worth mentioning is James Jones, & it looks like Cobb is now the main 4th WR for Green Bay, meaning Jones can pretty much be dropped at this point. It is going to take a injury to move him up.
