Robinson rushed for 108 yards on 18 carries -- 90 yards in the first half alone -- in Jacksonville's 27-13 loss.
Robinson's biggest play came on a 41-yard burst on the second snap from scrimmage on a fake reverse.
Bradley wasn't emphatic when asked if the Jags would label Robinson their No. 1 back, but he agreed the running back has played well enough to earn that role going forward.
The Jags might struggle through growing pains for the rest of the season, but they've started to figure out how to deploy their Denard weapon.
