Carroll was interviewed at Fargo last summer and was asked if he would be a 97 or a heavy in college. He said he was a little under 5'11", if he grew another couple of inches he would go heavy, otherwise probably 97.
It's possible we go 174 Thompson 184 Robb 197 Carroll 285 Mullen. That would be ideal. It feels like Mullen is holding out for football offers though, so I don't know how likely it is. Either way, I could see Carroll going 97.
Also, he's another one of those top recruits who has said the Olympics is his ultimate goal. UPenn probably has the 2nd best RTC after PSU. If he did flip to us, it would seem to indicate good things coming about the CWC.
