Mixed bag for Bears’ rookie class on Day 1 of training camp as WR Luther Burden III remains out

It’s going to take the Bears awhile to figure out what they’re getting from their rookie class, especially as some of the top players they drafted deal with injuries.

Tight end Colston Loveland, the No. 10 pick, was on the field for the first day of training camp Wednesday, but was limited. General manager Ryan Poles indicated there likely will be a ramp-up period as he recovers from shoulder surgery.

Second-rounder Luther Burden III, a major investment at wide receiver by Poles and coach Ben Johnson with the 39th overall pick, didn’t practice Wednesday as he recovers from a hamstring injury. Cornerback Zah Frazier, a fifth-rounder, also was out with an injury.

On the offensive line, second-rounder Ozzy Trapilo got the first shot at the starting left tackle spot, while veteran Braxton Jones and second-year lineman Kiran Amegadjie worked with the backups. Johnson has said it will be an open competition among the three, so it’s likely Jones and Amegadjie will get their turn shortly.

Defensive lineman Shemar Turner came up limping late in practice, but defensive coordinator Dennis Allen said he looked fine.

The Bears’ first- and second-rounders, four of the top 62 picks, are pivotal as Johnson and Allen try to tailor the roster to their schemes.

The Bears are projected to have one of the best offensive lines in the NFL after overhauling in the interior by acquiring guards Joe Thuney and Jonah Jackson and center Drew Dalman, but left tackle remains a significant question.

Jones missed 11 games over the last two seasons and struggled before getting hurt last season. And teams usually draft tackles in the first or second round with the expectation that they’ll make an immediate impact. The Bears likely hope Trapilo will win the job and Jones will be a reliable swing tackle behind him and right tackle Darnell Wright.

Burden, meanwhile, is an enticing playmaker alongside receivers DJ Moore and Rome Odunze, but has a lot to learn and can’t afford to miss much time in the preseason. The same is true for Loveland, especially given Johnson’s proclivity for playing two tight ends together.

Turner has some margin playing behind an experienced first unit on the defensive line, but Poles is looking for “waves” of defensive linemen modeled after the defending champion Eagles’ group.
