Bowles liked what he saw from Williams in limited action last night.
"He got off the ball some," Bowles said. "I've got to look at the film and see what he did."
Richardson, who Williams replaced on the first-team as he awaits further league punishment for his offseason actions, was complimentary while also being critical of the rookies debut.
"He did some good things," Richardson said. "He needs to play with his hands more [while engaging offensive linemen], and not his head. He just has to get his technique up a lot more. But as far as the aggression, he did that. He handled himself."
Williams, who played in only one quarter last night, knows he still has plenty to work on.
"I'm still kind of thinking a little bit because I'm still not used to reading plays before they develop," Williams said. "That's one thing that the guys I play next to are really good at. They see the play before it happens. I'm still learning the playbook a little bit, so I'm still thinking sometimes."
He learned quickly it will take more than his raw talent to succeed at the NFL level.
"It definitely has surprised me, especially playing the d-line position, where you think you don't have too much pressure on you," Williams said. "You really just had to play the lineman [in college] and find the ball. Now, we have to make sure that we're in our gap, make sure we slant to the right spot. There's way more thinking to do."
