I give the Panthers credit for wanting to resolve their questions. The problem is that injuries have complicated the decision-making.
Scout.com first broached the topic and I concur with their selections, in particular this one.
Which Wide Receivers Will Make the Roster? The wide receiver position has been highly competitive and right now there is only three players who are locks at the position with Kelvin Benjamin, Ted Ginn Jr. and Devin Funchess. After this group, Philly Brown, who is entering his third season, has to also be confident in his spot on this 53-man roster.
