I agree with you in general. I must admit that you seemed to know Suns mood much better than me, but we should always ask ourselves, is there any particular reason that a team would like to win big? Playoff teams know that NBA is a marathon race and you have to save your strength when you can. That is one of the reason that Minni holds up well the line in road games. They are hungry and always give 100% percent because all of them young players (besides Walker) with something to prove. On the other hand, most teams wouldn't like to beat a nice team like Minni when they are down. Suns are on great run and this is their last road game. They just want to wrap things up, put another W and go home to propare to Heat and Jazz (I know they have bad blood with Jazz, but why with the Heat?), so Minni should lose by 5 - 7 points, no more I believe.
Loved your way of thinking Tuck.
