4. Roquan Smith
Remember, at this time last year Roquan Smith was sitting behind Nick Kwiatkowski is Week 1. That really happened. Since then, Smith is grown is huge ways. However, with his slow start thanks to a missed training camp, the team rode with Danny Trevathan as their play caller.
It can be argued that the reliable play caller in Trevathan would have kept that role last year no matter what. However, as he transitions to the end of his career, and Smith ascends in the new Chuck Pagano defense, all thoughts are that the defense will be for Smith to call.
Smith should be ready for it, but this is a big game for him. He will be squaring off with Aaron Rodgers and an offense we have not seen before. He will have Trevathan beside him, but the outcome of his first game calling plays could be a key difference in the game.
