The Bulls wrapped up their first double session Tuesday night. The morning practice featured a spirited scrimmage. The evening session was more cerebral.

The team will hold two-a-days for a second and last time Wednesday.

"We did two last year," Bulls coach Tom Thibodeau said. "In the morning session, it's pretty intense. The evening session is more cleaning things up, making corrections, watching some film and it's more of a mental practice than it is a physical practice. But, again, you're trying to build your habits and you want to show that you're capable of concentrating over a long period of time. So we're not going to do anything heavy tonight."

The evening practice included film study. Thibodeau had his team watch film of things they did well and not so well last year.

"Trying to make those corrections, learn from it," Thibodeau said. "Then when you're studying teams, right now it's more the things that occurred during the game that you know you're going to see again that you want to be ready for. The more we study, the better we'll be. Of course, it's the same thing --- it's about building the right habits and these are things we'll be doing all season long. Starting now helps you build those habits."
