As aggressive as UNO plays the PK especially on top the umbrella should work if the puck is moved quickly...tape to tape.
A couple times NS got puck in high slot alone and passed further out.
UND carried the play down 2.......& it wasn't because UNO went into the prevent D shell that UND is known for. The game was tied at 2 more because of what UND did in the 3rd than anything UNO did or didn't do.
