Without Davante Adams in the lineup the last three games, the Rams have utilized 13 personnel (three tight end sets) with 47.2-54.8% of their offensive snaps. It has left Konata Mumpfield a part-time player. Last week, Konata Mumpfield had only a 42.5% snap rate and a 44.4% route share. In Weeks 2-3, with Davante Adams active and Nacua out, Mumpfield had a 71.8% snap rate, a 66.7% route share, an 11.6% target share with 1.69 YPRR, and an 11.7% first-read share. Mumpfield isn't a high-end target earner. I expect Mumpfield to be the primary receiver with all the tight ends this week as the full-time option, based on his ascension earlier in the season and his ability to help in the run-blocking department. That's not something the Rams should be asking Tutu Atwell to do often. The Cardinals have the third-highest two-high rate in the NFL (65.5%). In Weeks 2-3, against two-high, Mumpfield saw his target-per-route run rate jump from 14% to 20% and his YPRR jump from 0.97 to 2.76. Now, this is only a 62-route sample, but it's worth noting. Over the last five games, Arizona has allowed the 14th-most yards per target to perimeter wide receivers. Zoom out to the entire season, and they have allowed the third-most yards per target and the fourth-most fantasy points per opportunity to the position. Mumpfield is a decent flex this week with a wonderful matchup. My biggest concerns for Mumpfield are his ability to earn a higher target share and Matthew Stafford's passing volume.
