unfortunately I think the current style of play is quite susceptible to "reffing influence"...as opposed to, say, a team that scores from a lot of 3pt shooting...
dribble drives can either be called closely or refs can let everything go...as we saw a huge difference in the 1st and 2nd half vs Pitt...and subsequent results.
plus Duke probably gets the best homecourt reffing of any team i've ever seen.
this spread scares me a bit...
but i think it is based on what happened in Maui...
and this is a different team.
havent watched Duke play but I predict a competitive game.
Sidenote: and its almost like they lifted the number straight from Kenpom: Duke is +23 and Su is +9 = 14 point differential
