Hughes said if he and Kakko become the first two picks, it will add to the rivalry between the Devils and Rangers.
"I think it's good competition," Hughes said. "Every year the potential No. 1 and No. 2 picks are competing with each other. I know we had a great year and I think we'll be linked to each other for a lot of years with the Rangers and Devils right there. I'm excited, and I think it's been a good year for both of us."
Hughes led the NTDP with 112 points (34 goals, 78 assists), 2.24 points per game, in 50 games this season. He holds NTDP career records for assists (154) and points (228), with a 2.07 points per game average in 110 games over two seasons.
Hughes will take his first of seven combine fitness tests at 10 a.m. Saturday. He said he enjoyed his 10 scheduled interviews with NHL teams this week, including the Devils, Rangers and Blackhawks, who have the No. 3 pick.
