McCarthy is about three years younger than Penix and Bo Nix, who are the two guys he will probably be closest to in draft rankings. I like Penix of that group but the case for McCarthy is that he has more upside I suppose.
Reminder that the Gophers had 19 transfers out last year: https://gopherhole.com/boards/threads/official-2023-roster-movement-thread-whos-in-and-whos-out.108980/
10 at this point isn't super unusual, but we'll see how many more guys leave.
