Matt Russell backed Arizona +3 on Monday night, arguing the market is over-penalizing the Cardinals for starting Jacoby Brissett. He noted the spread opened Cowboys ‑3, slipped to ‑2.5 when bettors hoped Kyler Murray might play, then snapped back to ‑3 once Murray was ruled out, implying a 6% swing in win probability that the data simply doesn’t support. Brissett’s small sample (64% completion rate, 7.4 YPA, 4-1 TD-INT) grades 14th at PFF, actually ahead of Murray’s 17th-ranked mark (6.0 YPA, 6-3 TD-INT). Arizona has lost five straight, but none by more than four points, and their defense ranks seventh in opponent EPA per play in neutral situations after turnover noise is filtered out. Meanwhile, Dallas still trades at an inflated rating that stems from a preseason win total of 7.5; the Cowboys’ defense remains vulnerable to any healthy offense. Russell framed the matchup as a coin flip and called the full three points on the underdog a clear buy.
