That's why Cooper isn't concerned but also why he isn't rushing back from the heel injury. The hope is the less he does now, the more he'll be able to do later. For what it's worth, Cooper has remained engaged in his team's activities this August. It's the most he can do given the modifications being made to the offense under new offensive coordinator Kellen Moore. Cooper said things will be "dressed up differently" but it's all familiar to the fifth-year veteran.
