You can't focus on all-star status. From the standpoint of play so far, Lowry and DD have put up all-star numbers. For instance, DD is first in the East among SGs in PPG. Even if this continued to the all-star break he wouldn't make it because it's a popularity contest.
In my opinion, all things considered,
Bargnani has proven all he can be is a 6th man on a marginal playoff team. He basically plays like Kleiza. Ride him if he's hot, bench him if he's not. This is made worse by his frustrating tendency to give you nothing at all when he isn't the focus of the offense.
