An undrafted free agent, Proehl is competing with Chad Beebe, KJ Osborn, Olabisi Johnson and fifth-rounder Ihmir Smith-Marsette. The Vikings rarely feature their third receiver, but that could change with Kyle Rudolph gone. Proehl, who had a 47/577/4 line in nine games for ECU last year, would have late round Dynasty value if he finds his way into three-wide sets.
