The Facts: The Bears spent their offseason program force-feeding Trubisky a new playbook, seeing what he could handle, and were pleased by the outcome. Training camp will be all about fine-tuning. Quarterbacks and rookies arrived at Olivet Nazarene University in Bourbonnais on Monday, ahead of the official reporting date Thursday. Trubisky’s success — and that of the offense Nagy was hired to drag into the 21st century — will start with how the second-year quarterback can process those 16-word play calls. “You’re trying to learn and memorize,” he said, “and to try to forget what you did in the past.”

Diehards Line:The good news? Nagy’s offense, Trubisky said, makes more sense than that of former offensive coordinator Dowell Loggains, which Trubisky ran as a rookie. “It’s more complex, but it’s easier [to execute], as opposed to simpler but more difficult,” Trubisky said. Nagy, QBs coach Dave Ragone and coordinator Mark Helfrich taught the scheme with a logical progression. Trubisky knew he was being challenged and wanted more information. “I feel like that’s how it should be done, because it’s a more advanced offense, but we were able to pick it up so quickly over the summer because of how they taught it. And how everything fits together.” Trubisky is clear there’s no comparing his second season to his rookie year. He knows what to expect now.
