I would probably give Sasser minutes before Ron.
They just held Orlando to 33% from the floor and didn't let them break 100. In today's game that is great defense. Ron pretty much only brings defense to the table. They need someone who can hit a shot.
I don't like Sasser and think he is pretty bad. But Jenkins has been awful so giving Sasser some of his minutes won't hurt anything. Maybe he knocks in a couple of threes and loosens up the Magic defense a bit.
Odds are Sasser will also be terrible. But give it a shot.
