Mumpfield failed to secure his only target during Sunday's 37-20 victory against the Cardinals. The seventh-round pick out of Pittsburgh had a fairly quiet rookie year, finding a modest amount of playing time as a backup but never really gaining much momentum on the stat sheet. Mumpfield finished the regular season with a 10-92-1 line on 23 targets, ahead of only Blake Corum's 36 yards for output on the season. There were a few positives for Mumpfield, as he was on the field for all 17 regular-season contests, and he saw regular usage as a primary backup for Puka Nacua and Davante Adams (hamstring) on offense alongside Xavier Smith after mostly staying on the bench for the first six games of the season. Mumpfield will get his first taste of the NFL postseason on Saturday, as the Rams travel to Carolina for a wild-card round showdown.
Mumpfield secured two of five targets for 10 yards during Monday's 27-24 loss to the Falcons. For the second straight week, Mumpfield brought in less than half of his targets from Matthew Stafford, including an overthrown pass in the second quarter that Jessie Bates intercepted and returned 34 yards for a touchdown. Mumpfield has gotten an extended look in the last six weeks, with at least 20 snaps played on offense during each contest, but an 8-80-0 receiving line on 17 targets over that span doesn't inspire much confidence for fantasy purposes. Week 18 against the Cardinals still has meaning for the Rams in terms of playoff seeding, but even with Davante Adams (hamstring) still recovering from injury, Mumpfield's production seems unlikely to deviate much from his recent trends.
Mumpfield secured three of eight targets for 40 yards in the Rams' 38-37 overtime loss to the Seahawks on Thursday night. Mumpfield helped fill in for the sidelined Davante Adams (hamstring/knee) and drew the second-most targets on the night from Matthew Stafford, although he still only got to half of team leader Puka Nacua's total. Mumpfield wasn't efficient with his opportunities, but he still finished with new career highs in receptions, receiving yards and targets. Mumpfield could continue in an expanded role in a Week 17 road matchup against the Falcons on Monday night, Dec. 29 if Adams remains sidelined for that contest.
