As it turns out, a Clemson offer does mean more.
I was doing some research for the morning recruiting story, and it's interesting to see how rival schools approach recruiting (and how success allows you to modify your approach).
In going through the list of Clemson offers, the Tigers have handed out 70 offers for the 2021 recruiting class. Clemson has offered just seven wide receivers for the 2021 recruiting cycle and will take three of them. In contrast, as I pointed out this morning, South Carolina offered 40 according to 247Sports. Clemson has offered 70 players total across all positions.
