Tell me again how the Bears are supposed to be new and improved? Tell me how they're different from last year or the year before or the year before that? Okay, perhaps they will be on September 8 when football is played for real for the first time this season. Maybe Marc Trestman has it all under wraps for now and his offense will look like Chip Kelly's at Oregon once everything counts, in the season opener. But for now, halfway through the preseason, they look like, you know, the Bears.
