Not sure I'm buying what you're selling here. There are teams that are good at losing by a possession or two, and teams that are snake-bit by unlucky breaks late in games.
I see a team with an average amount of fight in it, that handles success poorly by giving away leads, and no-shows for extended periods with sloppy, unfocused play. For this team to get over the hump, they need greater determination and focus than we've shown. The raw talent is there, but the mental discipline and hunger isn't quite. When I see a team that punches back hard, I'll buy in. Really hope we get that, but so far it's been disappointing to see us struggle when the game reaches crucial moments. This team has too much talent for moral victories --that's just an excuse for missing the tourney.
