Rubio out. Exum out. Favors out. Neto and Royce O'Neale (who are both borderline NBA guys) having to guard Harden and Chris Paul took Rudy out of the paint way too much. They've done much better against Houston this season with Exum and Rubio healthy. So yeah, I guess Rudy's lack of switchability hurt, but only because the Jazz were running with the third string PG.
But look at the last few times Utah has played GSW (both this season and last season). They match up very well. And the only Jazz loss in the last 5 games was a 1-pt Jerebko tip-in.
