When first announced I thought the new tripping even if you hit the puck first was sketchy, but I'm glad they saved it a bit by making it not give a penalty shot if done on a breakaway.
"These are together because former Stars weep. Marty Turco is somewhere shaking his fist that he is not still around to take advantage of the extra area (bonus question: does this mean more or less puck gaffes for Mike Smith?), and while I don't believe Mike Ribeiro has ever done a true spin-o-rama, but I'm sure he's got some move in that bag of tricks that involves one.
Other than that, these are more procedural changes that will affect individual players and teams (depending on how well a given goalie handles the puck, obviously) than overall game flow."
