that is why you want to forsee this and stash the super sleeper away before the mad dash....many tired this with morgan last year and it didn't pan out. If Knox continues to get high praise many will do the same with him.....
Keep in mind that official training camps haven't started yet. This is why I dislike any draft of any type that occurs before late August. In this context, if I was drafting this week/weekend, I'm looking at Bennett and/or Knox with late round picks. If Chicago acquires a clear-cut #1 WR between now and week 1, neither of those guys is draftable unless you're in a very deep dynasty league.
As far as the Morgan comparison, it's a fair one, but Knox's QB situation is much more favorable than Morgan's was going into last year and he still may emerge given the opportunity.
Like I said, it's still early yet.
