In due time, bud.
Because there's still stuff Kasper can learn in the AHL. He'll get way more shot opportunities playing PP1 in GR.
Generally speaking, a player needs to learn how to shoot BEFORE playing in the NHL. Otherwise you wind up with Helm, LGD, Abby, Raz, Joey, Zadina, Perlini, Brome, Sheahan etc. The NHL is not the place to learn how to score. (Note that 5 of those players I listed were first round picks, high draft position guarantees nothing.)
Ray skipped the AHL because he showed scoring prowess in preseason. Kasper got set down because he didn't. Let him play a few games in GR. Hope Talbot stays hot in the meantime.
It was all Talbot, the D had more than their fair share of mistakes. He absolutely stole the game. Preds also had no puck luck, they had multiple chances where a lucky bounce would have lead to a wide open player getting a shot.
