Had Clayton or Sims signed with us originally, they would have been the crown jewel of their respective recruiting classes. And Ezzard is the first 4* wide receiver we've had in our roster since Calvin Johnson, so that counts for something. We did really well in the transfer market, especially if you consider Tyler Davis and Jared Southers to be apart of that. Davis is someone the staff thinks incredibly highly of, with potential for an All-ACC season.
Regarding the OP question, I don't think Sims will get a waiver. Ezzard might be able to get it the same way that Tathan Martell got one for a coaching change. Mark Richt (also acting as the OC?) kind of up and left pretty abruptly, which gives Ezzard a case for transferring. I think Clayton has the best case though, considering he has a child and is arguably moving closer to family. He's also a RS JR, so the NCAA might allow him to play because he's already been around awhile and was punished by injuries.
