Mike Pettine got by with a little help from his trusty, laminated roster card Friday as he paced the practice fields behind the Browns' facility in Berea.

The second-year Cleveland coach had plenty to watch at the first day of rookie mini-camp. One year since the Browns plucked a number of contributors from last year's tryout players, Pettine and his coaches evaluated a group that was significantly larger than the first.

The team's 12 draft picks, four undrafted free agent signees and a handful of first-year players who were on the roster before the draft were joined by 50 tryout players who came to Cleveland from Manitoba to Rancho Cucamonga, California -- from Florida State to Colorado State-Pueblo.

Pettine described the scene in simple fashion: "Win-win."

"We give guys an opportunity to come out here that maybe fell through the cracks with a lot of the tryout guys and it allows us to do 11-on-11 work," Pettine said. "Like we found last year, we found three guys that made the 53 in this. It's just great to be able to get these guys on film and get them evaluated."

Wide receiver Taylor Gabriel, defensive back Robert Nelson and defensive back K'Waun Williams were last year's tryout players who went on to make significant contributions as members of the Browns' 2014 53-man roster. Defensive lineman Jacobbi McDaniel, who was a member of the practice squad and appeared in one game, was also a tryout player.

Because quarterback Connor Shaw, McDaniel and a handful of other players who were on the roster before the draft are still viewed as first-year players, they were able to practice with the rookies. Shaw and McDaniel, in particular, were praised for their contributions, as coaches lauded McDaniel for the pressure he applied from the middle of the Browns' defensive line while Shaw received a large dose of snaps alongside tryout quarterbacks Justin Worley and Rakeem Cato.

"Connor's been Connor, very quiet but just very solid, knows what to do, quietly has good command of the huddle, has a presence," Pettine said. "He's just not a real verbal, real vocal type of leader. He's been real solid. Prepares well, and it shows up on the field."

The Browns' 12 draft picks, of course, drew the most attention from camera lenses. The two-hour, 15-minute session served as the first official action in a Browns helmet for first-rounders Danny Shelton and Cameron Erving, second-round pick Nate Orchard, third-rounders Duke Johnson and Xavier Cooper, fourth-rounders Ibraheim Campbell and Vince Mayle, sixth-rounders Malcolm Johnson and Charles Gaines and seventh-rounder Hayes Pullard.

Mayle (fourth round, Washington State) was limited because of a thumb injury while tight end Randall Telfer (sixth round, USC) and cornerback Ifo Ekpre-Olomu (seventh round, Oregon) were in street clothes.

"We know things are always a little bit slow in the beginning," Pettine said. "They're kind of slowed down trying to process. We don't get too wrapped up into it, but I think with pretty much every guy that we drafted, at some point during today's practice, there was a moment of, 'Oh, that's why we drafted him.'"
