Takeaways from Day 13 of Browns training camp …

1. Brock of ages: As the DeShone Kizer bandwagon accelerates like the bus in the movie Speed, the Browns have to justify playing Brock Osweiler beyond just the point that Kizer “is not ready.” Quarterbacks coach David Lee offered a few positive observations of Osweiler before practice. “He did a lot of really good things [in the preseason opener against the Saints],” Lee said. “He threw the … ball to Kenny Britt [in the end zone]. Kenny’s got one foot down. If he can drag [the other] down, we’ve got a touchdown. He misses Seth [DeValve] about four inches going in. I mean, there’s 14 points in 28 plays or something. He was close. He was jacked up. He was feeling it. He’s doing fine.” Lee said that Osweiler is totally caught up to Hue Jackson’s playbook now. “He studies so hard,” Lee said. “I can’t tell you how hard he prepares. And he is excellent at the line of scrimmage. When I first came into this league … the first vet [I was around] was Vinny Testaverde. Then it was [Drew] Bledsoe after him. Then we had [Tony] Romo and [Chad] Pennington. This guy we’ve got, as far as at the line of scrimmage and in the huddle, he may be better than all of them. He is so clear. He’s talking in the huddle, at the line. He is just a pro in that area. I’m sure his time with Peyton [Manning] has paid off.” Lee agreed that we should see quantum improvement from Osweiler in Game 2 against the Giants.

2. Cornerback update: The idea of moving Jason McCourty to free safety has been pretty much scrapped. Defensive backs coach DeWayne Walker said that when the Browns go to three cornerbacks, right now McCourty is the third cornerback – first one in against three-receiver sets – ahead of Briean Boddy-Calhoun. “At this stage of it, McCourty [is third] based off his experience,” Walker said. “Not that we’d be afraid to play Boddy out there.” And when McCourty comes in, he and Joe Haden will play outside and Taylor drops down to cover the slot receiver. As an unheralded rookie claimed off waivers at the start of the year, Boddy-Calhoun had a good year, co-leading the team with three interceptions and starting six games. He played exclusively on the outside. This year, Boddy-Calhoun is also taking reps inside as the backup slot corner. Walker said the challenge for Boddy-Calhoun is “consistency in just being able to handle the load of what both positions entail. He’s fine. He’s a smart player.”

3. Is he No. 1?: Corey Coleman is pleased with the way his second training camp is being managed (he’s on a pitch count) to prevent hamstring issues. He said he has improved from a year ago in “knowledge of the offense and scheme, and stuff … proper depths of routes, and stuff … the big picture.” In March, Jackson implored Coleman to step up and be the team’s No. 1 receiver. So I asked Coleman what is his definition of a No. 1 receiver. “ A guy who makes plays when it’s called for him,” he answered. “A guy, you’ve got to be a leader around here because a lot of guys are going to look up to you. A guy who does the right thing when no one’s around watching … know that I’m trying to get better. I feel that’s what it’s all about being No. 1.” Is he on track for that? “I feel I am,” Coleman said. “I’ve been working my butt off each and every day [on] every aspect of my game.”
