Cody Hoffman's a very good receiver. He broke pretty much every receiving record at BYU (my alma mater) playing with a few mediocre quarterbacks. He isn't an elite athlete, but he just makes plays. He's got good size and hands, but he needs to work a little on his routes and strength to gain more separation at the line and on his breaks. Good teammate and hard worker.
I think he'll probably at least make the practice squad and if he contributes on special teams, could be an eventual 4th or 5th receiver in a year. Won't be an immediate starter or anything, but he's exactly the type of guy you want signed as an UDFA.
Here's a good summary of him from a BYU football blog:
