Last season, McNair received some on-the-job training when White Oak's starting quarterback missed two games with an injury.
"In those two games, he really proved that he can run the ball [and] can run the offense," Blick said. "He's a dangerous runner, he's a powerful runner."
Playing quarterback doesn't mean McNair won't see time on defense.
"We're weak at linebacker, this year, on the inside," Blick said. "Tremayne is going to have to play both sides of the ball. We'd hate to do that, but a guy with his talent has got to be on the field making plays.
"We'll try to spot rest him on defense, but we've told him that's he's going to have to play both sides and he's looking forward to it. As a coach you hate to do that, but we really don't have a choice."
McNair's defensive highlight tape is what made Duke and NC State offer scholarships.
"Once [Duke and NC State coaches] looked at the tape they really liked what they saw and boom it was pretty quick [with an offer]," Blick said.
"[McNair] is a high character kid. He has all the tools, the size, the strength, he's smart, great work ethic, [and] defensively he'll take your head off. He's a big time hitter. He'll stick his nose in there and I think that's what comes through on the tape."
Blick, who coached UNC's starting free safety Deunta Williams in high school, believes more offers are on the way.
"Now that the linebacker coach from [NC] State, [Andy McCollum], is now going to Georgia Tech to be the recruiting coordinator, I expect Georgia Tech to be interested," Blick said. "I know Coach McCollum was high on Tremayne. Coach McCollum looked at the first three plays on [McNair's highlight] tape and said ‘That boy s a ball player.'"
North Carolina is another school with high interest in McNair.
"When Coach [Charlie] Williams was here, he said he really liked what he saw," Blick said. "I don't know if they had evaluated the tape at that point. But I'm sure they've done that now, so we'll see where that takes him."
Williams invited McNair to UNC's Junior Day this weekend and UNC's camp over the summer. McNair accepted both invites.
"I'm really looking forward to [the junior day]," McNair said. "I've been to a football game [at UNC], but not a basketball game."
McNair has also attended a football game at NC State. Earlier in the month, McNair had planned to attend Duke's and NC State's Junior Days, but both were canceled due to inclement weather.
He doesn't claim any favorite schools.
"It's all new to me, so I'm open right now," McNair said.
McNair doesn't expect to name favorites until after the football season.
"I want to make sure I make the right decision," he said. "I don't want to rush anything."
For now, McNair is focused on his basketball season - he's the starting point guard, averaging 17 points per game. McNair's third sport is track, where he participates in the long jump, high jump and triple jump.
