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

Roquan Smith, LB, first round: After a monthlong holdout, Smith is finally in camp and expected to make his pro debut on Saturday against the Kansas City Chiefs. He hasn't been able to show much yet after just a handful of practices, but the Bears remain optimistic he will be a linchpin for their defense for years to come.

James Daniels, OL, second round: Daniels has a chance to be an impact player for a Bears offensive line that is trying to find more consistency. The question is whether he will get a chance to start right away. Saturday's game will allow Daniels to put some more work on tape for the coaches to see.

Anthony Miller, WR, second round: Miller's name has repeatedly popped up throughout training camp as someone who has opened eyes. If he continues to develop a nice rhythm with second-year quarterback Mitchell Trubisky, he will become a much-needed weapon in coach Matt Nagy's offense even earlier than expected.

Joel Iyiegbuniwe, LB, fourth round: An early shoulder injury set him back at the start of training camp -- up to this point he hasn't been able to show much in the preseason.

Bilal Nichols, DT, fifth round: Nichols' size and versatility set him apart and have given him a chance to earn some time once the real games begin. He had a sack in Saturday's preseason win over the Denver Broncos and figures to get even more snaps against the Chiefs this week.

Kylie Fitts, DE, sixth round: Fitts has shown some flashes in the preseason and will provide depth in coordinator Vic Fangio's system. He has the athletic ability to bounce all over the field. He just has to prove he can stay healthy after an injury-filled career at Utah.

Javon Wims, WR, seventh round: Wims had a couple of receptions in Saturday's win and must have a strong showing in the final two preseason contests to nail down a spot on the 53-man roster.
