Register still receives letters and e-mails from schools like Florida State, Tennessee and N.C. State.
"[It's] nothing heavy," he recently said in an interview with CUTigers. "They're not telling me to call them or anything."
Firm with his pledge to Clemson, Register looks forward to his senior season at Dudley High School in Greensboro, N.C.
"It really hasn't started to hit me yet, but I know it will sooner or later. I'm really starting to feel like I'm being looked up to, stuff like that," Register said. "All in all, I just wanted to end my senior year with a ring."
Like he's done the last two seasons, he'll play middle linebacker.
"Pretty much, I'm the quarterback of the defense at the MIKE. That's been pretty much the same every year since sophomore year," Register said.
On offense, he'll work at tight end.
"I just want to do my part to help us win, play my all, push other players to go hard and I'm going to push myself even harder," Register said.

"I talk to coach Caldwell every now and then. Coach Caldwell just sent me a postcard [on Wednesday]," Register said.
Register has yet to plan any visits back down to Clemson, but he does foresee big things out of the Tigers this fall.
The No. 25 outside linebacker in the class of 2014 Clemson will begin its ACC title run with an out-of-conference win over Georgia.
"That's going to be a pretty good game. I think it's going to be a real good game. But they have Tajh Boyd back. I think Clemson is going to pull it out," Register said.
During his junior season, Register had 111 tackles, 10 tackles for loss, seven sacks, five forced fumbles, two interceptions and three pass breakups.
In nine games as a sophomore, Register had 90 tackles, 10 sacks, five forced fumbles, four interceptions and three pass break-ups.
