Coach Raheem Morris said Miller has played well enough in live scrimmages to be considered the third tackle behind starters Chris Hovan and Ryan Sims.
"If I was making a decision based on OTA (organized team activities) days and if I was making a decision based on these couple weeks of camp, you'd have to say Roy Miller is going to be in the rotation," Morris said. "He has really stepped up and played well.''
Rookie DT Roy Miller"This heat is something," Miller said of midday temperatures in the low 90s. "I should be used to it coming from Texas, but it's not this humid down there. Sometimes this feels like a big ol' cloud of humidity on you."
Miller, a third-round pick, also is trying to adapt to Jim Bates' new defensive scheme, which is unlike Miller's college playbook at Texas.
"Last year, I did something completely different than what they want here," Miller said. "I was a one-gap type player, straight upfield. Now I'm playing more on the blocker. It's a transition, and I think I'm doing pretty well with it. The older guys, like Chris Hovan and Ryan Sims are giving me a lot of support, and I appreciate it."
