The Salt Lake Tribune (Ross Siler) reports: There’s still 17 days to go until opening night for the Jazz, but the Andrei Kirilenko experiment at sixth man moved a step closer to reality in Sunday’s 93-80 preseason victory over the Portland Trail Blazers.   Jazz coach Jerry Sloan opted to start C.J. Miles and bring Kirilenko off the bench again, even with Carlos Boozer returning from a sore hamstring, and Kirilenko followed through on his pledge to help bring the new role to life.    Kirilenko hit a shot 14 seconds after checking in and factored into all five scoring possessions to end the first quarter. He went on to lead the Jazz with 15 points, five assists, three rebounds and two blocks in 25 minutes.
