• FB Obafemi Ayanbadejo: It remains to be seen whether it will be enough to get him a spot on the roster, but Ayanbadejo no doubt made Coach Dave Wannstedt's decision more difficult. Ayanbadejo led all Dolphins rushers against Chicago with 28 yards on four carries, including a gutty 8-yard touchdown up the middle, and he also had three catches for 35 yards.
• WR/PR Albert Johnson: Johnson't ticket to the roster is as a kick returner, and he again showed explosiveness against the Bears. Johnson gained 34 and 29 yards on his two kickoff returns — not overwhelming numbers — but he continues to have the look of someone who's going to break a long at any time.
• S Scott McGarrahan: McGarrahan is involved in a tight battle at safety, and he had a strong night on defense. Given his tremendous ability on special teams, Thursday night's defensive performance might have sealed his spot on the roster.
• DE Adewale Ogunleye: Ogunleye's roster spot has been secure for a while, but he cemented the starting left defensive end job by getting another two sacks against the Bears.
On the flip side, guys who didn't help themselves included WR Jeff Ogden, who looked like he was pressing. He dropped a pass in the first half, something that is unusual for him. He also committed a false-start penalty.
None of the three guys competing for the fourth defensive tackle spot — Henry Taylor, Ernest Grant and Dario Romero — did anything to distance themselves from the pack. The Dolphins were porous against the run, which doesn't speak well for the performance of the interior of the defensive line.
