After loading up last year, who's realistically in the market for a 1st round receiver?
Miami Dolphins (not happening with the #3 so it'd have to be the #18, unless they trade down the #3 if Sewell isn't there)
Chicago Bears (depending how FA shakes out... maybe)
Tennessee Titans (if Corey leaves in FA)
TB Buccaneers (depending FA)
Green Bay Packers (stupid Funchess deal is going to make signing their FAs hard so they need to reload)
The bolded teams are the only ones I could see actually doing it.
The others would depend on how FA pans out, but they have other needs and could easily take a WR in the 2nd/3rd.
