How could he "end up playing for the Hurricanes"? Is he planning on withdrawing his commitment to TAMU and switching to UM? Jimbo isn't going to let him transfer just because he's homesick.
If Stewart does try to transfer, its almost certainly going to be because he isn't starting at TAMU. And why would Cristobal have interest in a player that spurned him and then isn't good enough to play at TAMU? Fortunately Mario is a good enough recruiter that if Stewart tries to come around again, Mario can say, "Sorry, son. You had your chance."
