If this is true, it may make sense that he withdrew from the portal. I highly doubt that he would have many teams calling if academics are an issue (which we know they are, bc I have mentioned many times that was the case, clear back to HS).... Guessing that Rhule sees the talent....Betts options were limited, to say the least.... so come back, possibly cash in on some NIL..... join team so he can get the academic support that athletes get... become eligible for Fall practices.
Now, this is just the rumor from Sip, so maybe, he just really appreciate Rhule compared to the old staff and wanted to stay a Husker and will be a full participant and eligible to play right away.
I have also seen the same questions from other media guys. I'm not sure anyone really knows what his academic status actually is but I don't think anyone is sure that he has even been going to classes.
