Agree on Ennis "maturity." I also think a combo of Pritchard and Benson need big games, too: if 4 of our 5 starters play great, we have a chance. No less. It may take the game of their lives, literally, and all on the same night to beat NC. Those guys are just so deep, long, fast, and accurate.
Plus... few teams ever do well at the next level the first time. Call it jitters or lack of confidence or just being surprised by the intensity. I wouldn't bet on the Ducks for all these reasons, but I know Altman has the coaching chops to draw up a win. It's a matter of execution: I think we have the talent, but like I say, it's unexplored territory for the program and that's important.
