THE KEY MATCHUP

Lions DB Loucheiz Purifoy vs. Riders SB Naaman Roosevelt

Roosevelt is the key to the Roughriders’ inside passing game. Therefore, he should expect to see plenty of Purifoy, a defensive halfback. Roosevelt was able to get behind Purifoy once last week, but Glenn was hit as he threw the ball and a wobbler of a pass fell incomplete. Given more time, Glenn is sure to look for Roosevelt — the Roughriders’ most consistently effective receiver. Wideout Duron Carter is flashier, but his play can waver. Roosevelt is known as a steady contributor.
