Why Didn't Lions Trade for a CB at Trade Deadline?

The Detroit Lions did not acquire a cornerback before the NFL trade deadline, despite the position being viewed as a major need. The team instead traded for safety Andre Cisco and appears set to rely on its existing cornerback rotation, including Roger McCreary, Ennis Rakestraw, Rock Ya-Sin and Khalil Dorsey. Heavy reports that limited available options and confidence in the group helped shape the decision.
