The running back led the team in rushing yards during the game, gaining 31 yards off seven carries.
The 23-year-old told the team's website: "I felt really good, energised out there, was in shape, game shape. It's different than practice shape. You never get into shape until you get into the game. I feel like I've got fresh legs right now.
"You don't have to do all this shaking and this and that. If they get up on you, you make a move and go, or you've got to run them over. It's either one. For me, it's, 'Get past the defender and make him miss, or he's going to hit you'. A lot of running backs don't like to get hit.
"Like I told [Coach Rob Chudzinski] in the springtime, I'm going to be in the best shape for a running back that he's ever seen. When they took me out, I was mad. I was trying to get back in. I wanted to finish. I wanted to finish that whole half and go into the third quarter."
The Browns play the Chicago Bears in their final pre-season game on Thursday.
