One of the great things about the bench mob last season was the tremendous chemistry the group had together. Chicago famously let every bench mob player under contract leave to bring in a new, cheaper group. They were all cut from the high character cloth that Forman/Paxson are famous for going after.
Kirk Hinrich obviously still fits that mold. He knows the organization. He knows a bunch of the players. Chemistry wise, he should fit right back in with the group easily, and his attitude will certainly work well under Thibodeau. While many have questioned his performance over the past couple of years, the way he goes about his business and fits into the locker room should be a big plus [and hopefully the performance will be better than people think].
Nate Robinson's a very loud personality both on and off the court, and it will be interesting to see how he fits into a locker room that hasn't really had a personality like his in it before. I wouldn't characterize him as being a bad character guy, but he's a very different type of character guy than the Bulls have had in the past. In some ways, I think the Bulls might need a shot of his character. Sometimes you need someone to rile everyone up. Too much of that is a bad thing, but not enough of it isn't good either, and the Bulls have likely been on the 'not enough' side of that equation for the past five or six years. While it could obviously go either way, I think Robinson's personality will really help this locker room.
Nazr Mohammad is one of the league's great guys. He's going to fit right in with the organization. He'll do everything asked of him and gives the team an excellent Kurt Thomas-esque type of leadership and presence. He'll be a big plus to the chemistry of the group and provide some veteran leadership doing all of the little things a team needs.
Marquis Teague seems like a big question mark. The Bulls obviously gambled on his talent, but we saw in summer league that he was a fairly low effort guy, and it also explains why he may have been sitting there at the end of the draft. He's also a young guy who likely needs to figure things out and hasn't yet entered a stage in his life where his ass wasn't kicked. It will be a huge wakeup call for him to go from BMoC to scrub hanging on in the league and having to outwork everyone because he's on the low end of the talent totem poll instead of the high end. The Bulls could be a perfect environment for him because of all the solid guys around him to help him, or it could smother him due to lack of opportunity.
Marco Belinelli once refused a D-League assignment with the Warriors which is certainly going to give a guy a questionmark in the attitude column. However, he was coming over from Europe where he gave up good money to play in the NBA and wasn't given much of an opportunity. It's easy to see why he wasn't so happy with a D-League assignment. I suspect that Belinelli will be comfortable in his Bulls role and he choose to come here as a free agent and wasn't locked into a long term under market value contract. He had a reputation as a somewhat low effort player at times coming into the league as well. I wouldn't call him a character risk, but I don't think he's a character plus either.
All in all, this group of players will need to prove that they can gel together to get the same "greater than the sum of their parts" performance that the previous bench mob did. One thing that will work in their favor is Tom Thibodeau is not afraid to trust anyone on the team. Not only will he gave everyone a legitimate opportunity to succeed, but he'll do so at the biggest moments while completely ignoring the salary, reputation, and ego of the team's members.
His philosophy has been successful because of the tremendous buy in of the players. He'll need to get a new group to buy in again this year. I'm cautiously optimistic that the new bench mob can match or even exceed the performance of the old one, but they'll need to find the right fit together to do so.
