I gotta be honest, with Strev at QB I like Bailey and Petermann over Whitehead and Demski too. Bailey and Petermann are more traditional receiver types that give Streveler nice, easy pass options. I really like what Whitehead and Demski bring to the table in play making ability, and with an experienced QB they get my vote, but they do not have the same ability to get consistently open and provide their QB with safe medium range targets in the holes of the zone.
Personally, I was hoping the Bombers were going to give Petermann more playing time this year. Bailey seems to have a natural receivers ability in his routes and nice soft hands.
