A breakdown of the Cleveland Browns' 2018 draft class and its progress after three weeks of training camp:

Baker Mayfield, QB, first round: The 2017 Heisman Trophy winner has played well, completing 18 of 33 passes for 287 yards and two touchdowns through two preseason games. Despite being the No. 1 overall pick, the plan is for Mayfield to be the backup to Tyrod Taylor this season.

Denzel Ward, CB, first round: The No. 4 overall pick, Ward has jumped right in to getting first-team reps on the Browns' defense. He has been battling an ankle injury over the past week, but coach Hue Jackson is still confident he will be a major contributor on defense.

Austin Corbett, OL, second round: Corbett has performed well with the first-team offensive line at left guard, playing between JC Tretter and Joel Bitonio. He felt like he made a big leap between the first and second preseason games and continues to improve.

Nick Chubb, RB, second round: Chubb struggled in the first preseason game against the New York Giants, gaining just 11 yards on 15 carries, but bounced back with 53 yards on 11 carries in the second game against the Bills.

Chad Thomas, DL, fourth round: After missing the preseason opener following sports hernia surgery, Thomas was listed as third string on the depth chart and saw action in almost half of the Browns’ defensive snaps against the Bills.

Antonio Callaway, WR, fourth round: The talented wide receiver had three catches for 87 yards against the Bills, showing what he can do on the field. But his off-field problems have continued with a citation for marijuana possession and driving under a suspended license. He is dealing with a groin injury, but Jackson doesn’t think it will be a big deal.

Genard Avery, LB, fifth round: He missed the game against the Giants with a groin injury and returned against the Bills, where he played 22 snaps and had one tackle.

Damion Ratley, WR, sixth round: Ratley has three catches in the first two preseason games, but has had a solid past week of camp. He has taken advantage of opportunities created by the trade of Corey Coleman and Callaway’s groin injury and has taken snaps with both Taylor and Mayfield at quarterback. He took some first-team reps on Monday with Callaway out.

Simeon Thomas, DB, sixth round: Thomas could be bumped up the depth chart for a few weeks after the injury to C.J. Gaines, which might be a chance for the rookie to show what he can do.
