These kids believe in their abilities. When a someone like Coach K walks into your living room, shows you his Final 4s, ACC titles and National Championships - then tells you the best players will play and you will have every opportunity to earn PT, you sign up. You don't become a top 50 player in your class in the country by not believing in yourself. Tucker probably thought he could carve out a role this year and then be a big time contributor next year. And I think that comes from his self confidence. There is nothing wrong with that, but you also have to make sure you have an accurate feel for your abilities and the kind of roster you'll be on. Duke is destroying everyone in their path lately - it's obvious they don't need Tucker and I'm sure he realizes it too.
Too bad too, because with Tyus drawing so much attention and Frank/OShae doing their thing - Tucker would have got A LOT of open shots for us this year
