In Part 3 of our Cleveland Browns training camp preview for the offensive line, we looked at three linemen who are likely competing for the final spot on the depth chart on the line. In Part 4, we look at the remaining four offensive linemen on the roster.
11. ANDREW MCDONALD - BACKUP OFFENSIVE TACKLE

Height: 6-6 | Weight: 310
Age: 26 | Experience: 2 years
College: Indiana
Note: Has played for several teams since 2012, but not with legitimate NFL experience.
Andrew McDonald signed with the Miami Dolphins in 2012 as an undrafted free agent. He spent all year on their practice squad but didn't make the team out of camp in 2013. Last year, he bounced between the Carolina Panthers, Seattle Seahawks, and Indianapolis Colts, only playing in two career games as a reserve. The Browns claimed him off waivers last December.
McDonald admitted that he was "Player A" in the Ted Wells investigation into the bullying that took place on the Miami Dolphins a couple of years ago. For those who aren't familiar with the report, "Player A" would make McDonald a victim, not a perpetrator, of the bullying.
McDonald is expected to compete for a backup role at offensive tackle in camp. I'm projecting him to play left or right tackle with the third-string offense.
Final Roster Odds: ~1%
12. KARIM BARTON - BACKUP CENTER

Height: 6-3 | Weight: 313
Age: 23 | Experience: 1 year
College: Morgan State
Note: Spent all of 2014 on the Browns' practice squad. ... Originally from Jamaica.
Karim Barton signed with the Philadelphia Eagles last offseason as an undrafted free agent. He played as a backup in three preseason games and played right tackle his final year at college. Philadelphia waived him in their first round of cuts, and the Browns claimed him off waivers.
Cleveland released Barton a week later but signed him to the practice squad, where he spent all of last season. Originally from Jamaica, the Browns did a feature story on him at the end of March, covering the issues with his parents and the admiration he has for veteran linemen John Greco and Joe Thomas.
Barton will compete for a backup spot at offensive guard this camp. If he doesn't win a roster spot, he'll have another shot at landing on the practice squad, but it's not often that a player stays on the same team's practice squad for two years in a row due to the influx of new talent that comes in.
Final Roster Odds: ~1%
13. TYLER LOOS - UNDRAFTED FREE AGENT OFFENSIVE LINEMAN

Height: 6-5 | Weight: 294
Age: 22 | Experience: Rookie
College: Northern Illinois
Note: Signed by Browns after a rookie tryout. ... Played tackle in college but could move inside to guard.
Tyler Loos is one of two undrafted free agents the Browns signed after a tryout at rookie minicamp in May. Our SB Nation affiliate has a full biography up on Loos. Here is a snippet:
"Tyler Loos has never been a mauler, but more of a technique player. The question might be whether he has the foot quickness and strength to play tackle in the NFL. But with his health issues hopefully behind him, we may see Loos grow into a more physical player since he will be able to focus on other aspects of his strength other than rehabilitating his legs."
Loos played left tackle in college, but it's up-in-the-air as to whether he'll assume that role on the third-team offense or move inside to guard like our Tim Miller thinks he will.
Final Roster Odds: ~1%
14. DARRIAN MILLER - UNDRAFTED FREE AGENT OFFENSIVE LINEMAN

Height: 6-5 | Weight: 307
Age: 22 | Experience: Rookie
College: Kentucky
Note: Signed by Browns after a rookie tryout. ... Played tackle in college but could move inside to guard.
Darrian Miller is the other undrafted free agent offensive lineman the Browns signed after a tryout at rookie minicamp in May. Miller was rated as a 6th or 7th round pick by Dane Bruglar of CBS Sports. Here's what Bruglar said about him in his scouting report:
"The Wildcats’ starting left tackle the past three seasons, Miller showed steady improvement over the years and stood out during East-West Shrine Game practices for his consistency in pass protection and promise as a run blocker. He doesn’t play with lateral explosion or lower body burst, limiting his range against speed rushers, although he works well in shorter areas with his flexible stance to stay square. Miller lacks the physical tools or consistent technique to be a reliable NFL starter at tackle and is a candidate to move inside to guard where he can work in small spaces – durable later round prospect."
Like Loos, it's believed that Miller, who played tackle in college, could shift over to guard. The Browns could experiment with both players at both positions on the third-team offense until they find the right combination in camp. At the end of the day, Miller and Loos are really just competing for a spot on the practice squad.
