Who Should I Start? Jermar Jefferson or Corey Kiner

Tuesday, December 31, 9:23 AM

Detroit Lions running back Jermar Jefferson was given just three attempts during their victory over the San Francisco 49ers on Monday evening. However, all three attempts were within the San Francisco ten-yard line. With David Montgomery (knee) sidelined, Jahmyr Gibbs has been deployed as the workhorse option in this backfield, but with the Lions having little to play for regarding their position in the standings, they opted to give Gibbs occasional rest on Monday evening. While Gibbs still finished the game with 18 attempts and four targets, he would have likely been given this goal line work in a must-win situation. Instead, Jefferson was given some high-value touches but could not punch in any of them as he finished with just nine total yards. In addition, Jefferson saw four fewer carries than the presumed No.2 option, Craig Reynolds. Fantasy managers should expect Gibbs to take on a three-down role during Week 18 and throughout the entire postseason, leaving just a handful of attempts for Jefferson and Reynolds.

Rookie Corey Kiner had a solid day in his professional debut. In the 49ers' preseason opener against the Denver Broncos, Kiner led San Francisco's backfield in touches and yards, taking 10 carries for 45 yards and catching one pass for a two-yard gain. He also served as a kick returner, bringing one back for 17 yards. Kiner, an undrafted free agent, comes to the 49ers after back-to-back 1,000-yard seasons as a Cincinnati Bearcat and figures to see a lot of work in the preseason. San Francisco is unlikely to put Christian McCaffrey's health on the line so early, and Isaac Guerendo (shoulder) and fellow rookie Jordan James (finger) are set to miss multiple weeks while nursing injuries. Kiner will have his next chance to impress next week against the Las Vegas Raiders.
