Rip Hamilton's injury on Saturday will keep him out for a few games, possibly 3 or 4, about a week. Coach Tom Thibodeau has a number of options to fill in during Rip's absence and tonight it will be Marco Belinelli. Marco has been a starter in the league before. He can provide offense, which the Bulls need. His 3-point shooting will open the floor for others. His long range shooting has been pretty good thus far...he's at 41% which leads the team, but he hasn't gotten all that many shots just yet.
Another option is Jimmy Butler, but Tom Thibodeau would prefer to keep him coming in off the bench with the 2nd unit, pairing with Taj Gibson to provide the energy that they have been bringing all season. If given a chance to start, he offers a number of elements that Tom values....defense, rebounding and not taking bad shots.
Lastly, Tom could move Kirk Hinrich to the shooting guard and pair him with Nate Robinson at the point. I don't see this happening unless the opponent features a smaller guard tandem that Tom would like to match up with.
