Rodgers is probably listed as the WR2 on a lot of depth charts but it seems like Grant is making a push for this spot. As the video said, it's still early but it's a situation to keep an eye on as camp progresses. It's more about Grant's ability to be consistent and make plays that seems to be putting him in position to earn the WR2 spot.
