There always seems to be a receiver that becomes "the guy" in that offense that wasn't particularly on the radar. Cede was last year, Brown the year before, Westbrook before that, so on and so forth. QBs have their favorite targets that they bond with in spring practice and summer camp and I have this feeling it's going to be either Rambo or Haselwood this year.
I didn't take it as a knock, but there are some that will say "the Sooners are going to suck because so and so graduated or got drafted". There are always backups to the backups.
