Check this quote from nfl.com by Lee Woodall, now an Argo.
"I noticed that in the CFL they don't use the backs as a receiving threat," Argonauts linebacker Lee Woodall, a two-time Pro Bowl selection and a veteran of more than a decade in the NFL, told The Toronto Sun for a Sunday story. "But I'll tell you, if the Argos get Ricky, that's one of the factors you can put on your plate."
I hope he holds onto this concept when the regular season starts. Where did he get this idea that we don't use backs as receivers? It is a rarity in the NFL compared to here.
