The Rams and Cowboys will square off on Sunday afternoon with several marquee matchups all over the field.

This is a lopsided matchup that favors the Rams, as is the case every week when Donald suits up. Su’a-Filo was the backup left guard until Connor Williams tore his ACL, and he’s not exactly an above-average blocker.

Donald probably won’t have more than a few rushes where he’s one-on-one with Su’a-Filo, considering how often he’s doubled by opponents. That means Tyron Smith will give his fellow lineman some help with Donald, as will Travis Frederick from his center position.

Interior pressure is the best way to throw a quarterback out of rhythm, so Donald winning his reps will be critical.
