(cbssports.com)Slowly but surely, Sam Bradford is getting acclimated to life in the NFL. The No. 1 overall pick of the April draft joined veterans on Thursday at the first day of the Rams' minicamp. The former Heisman Trophy-winning QB from Oklahoma said that after OTA workouts and the first day of minicamp, things are starting to sink in. "The more I'm out there and the more reps I get, the more comfortable I feel," Bradford said. "From Day 1 to now, it's night and day how much more comfortable I feel just calling the plays in the huddle, getting to the line of scrimmage and making the reads. I feel really good with the progress I've been able to make." Coach Steve Spagnuolo felt good about that progress, too. "Today, we threw a couple of things at the quarterbacks from the standpoint of pressures. I thought all of them did a nice job and Sam stuck out on a couple of them," Spagnuolo said. "He looked real good on them. That's important." It isn't yet known if Bradford will immediately move into the starter role for St. Louis. Bradford is competing with A.J. Feeley for the starting job.
