"We want to see how each guy looks with each offensive line," Rivera said."It would be unfair to have one guy with the ones, one guy with the twos, one guy play against a one defense and the other guy play against a two defense and say one looks better. So we're most certainly going to mix and match, and we have to so it's a fair competition."
Rivera said Clausen was more consistent than Newton during Tuesday's practice.
"Cam threw some nice balls and threw some balls that were a little bit late, threw off his back foot, stuff like that," Rivera said. "Again, it's a work in progress for both of them."
