I agree with you on Newton's last shot. I think the plan was to set Stewart up for the shot and due to whatever reasons, Tristen lost sight of it.
Beyond that, I really don't see anything to complain about. Throughout the final eight minutes of the first half we had numerous opportunities to extend the lead to double digits and with the first five or six chances, the Zags cut the lead to around five. For te bulk of the last ten minutes of the game Gonzaga was a mini run away from giving us quite a bit to worry about. That wasn't a game where Hurley was going to give any real run to someone he doesn't fully trust yet. We have too many bodies that he does trust at the moment.
Be patient (I'm sure Stewart is). His minutes will come.
