They know who will redshirt and who will not . Nothing is going to change that much between now and Sep 3. The Coaches are just waiting and if somebody has a bad enough injury. They could take a redshirt off but they know who is ready to play by now .
You all did read the article, right? The first paragraph says: "Clemson coach Dabo Swinney talked to reporters after Friday's practice and gave an update on some of the offensive redshirt decisions on his football team.".
This is only for the offense. My guess is we will see a similar article for the defense soon. It sure is fun to have so many good players that we talk so much about who is and isn't being redshirted. GO TIGERS!
