I'm not so sure about that. Kimber is similar to Rucci & Fleming in the fact that their ratings as a prospect were higher than their ratings as a transfer. Kimber was a 4* 95 rating as a prospect but fell to a 3* 87 rating as a transfer (per 247).
Much like Grimes who chose MSU. He was a 4* 96 as a prospect but fell to a 3* 87 as a transfer.
I don't know how Fleming, Rucci, or Kimber will perform but they didn't live up to their original recruiting hype at previous schools and they seem to be looking for a school where they have a better chance to emerge.
Regardless, PSU needed CBs and Kimber is likely to see plenty of action. I'm just not convinced that he'll start. We'll see.
