"I have grown up a Duke fan. I really like the academics they have there. Coach Cutcliffe and his staff are amazing people. Coach Cutcliffe coached the Manning brothers, and both have won Super Bowl MVPs."
Sink has been impressed with Duke this season and the progress since coach Cutcliffe arrived.
"I am very happy with the way the season is going," he said. "One more win, and they are bowl eligible. I was happy when Duke hired coach Cutcliffe. I knew he would turn the program around. He has done an amazing job in two years. That just shows you his coaching ability."
Sink talked more about his relationship with the coaching staff.
"I have a great relationship with the coaching staff," he said. "Coach Jim Collins was my recruiting coach. They have talked to me about tight end and defensive end.
"The defensive ends coach [Marion Hobby] played at Tennessee and in the NFL. The tight ends coach [Ron Middleton] played at Auburn. They have a great coaching staff.
"I really don't have a preference where I play in college. Whichever position they see me being a better fit I would be happy to play. If I had a choice I would say tight end because I am more comfortable at the position. I wouldn't be upset if I switched though. I would be happy to play wherever."
Sink knows why the offer was extended so late in the season.
"I was a late bloomer football-wise," he said. "I was mainly a basketball player. My coach made some calls this season and told coaches they would be interested in checking me out. It was a big relief when Duke offered me.
Sink recognizes his strengths he'll bring to the Blue Devils.
"I feel like I have definitely improved my speed and strength," he said. "My blocking ability is probably my biggest strength. My strengths are my strength and speed for my size. I run a 4.7-40. I am 6-foot-6, 245-pounds."
Sink has recorded 31 receptions for 508 yards and five touchdowns this season. He recorded eight tackles and two sacks in his last game on defense.
Sink attended the Richmond and Maryland games in Durham with plans to return for the Georgia Tech game.
"The atmosphere this year has been really good," he said. "The stadium has been packed each time I have been up there. It has changed a lot from what Duke used to be."
