I would also not be surprised for Cael to do EVERYTHING he can to try to get him to flip. Cael left Iowa because he could not out recruit Brands in Iowa. Last thing he wants is for Brands to get a strong foothold in PA. There is a legit chance that half the lineup could be PA guys in 3 years. I understand that some of these guys may have been available because Cael has better options, but still not ideal for Cael.
Carl left Iowa because Pollard was too cheap to match/beat PSU's offer.
