Marks is getting 12.3 carries per game into a Buffalo run defense that gives up more than average. His 3.6 yards per carry is modest, but volume and a soft matchup create the opportunity for one 11-plus yard run. In a neutral script, Marks' workload and Buffalo's run-defense weakness make a single explosive carry a reasonable expectation.

Marks is averaging just 2.3 targets per game, and Buffalo's pass defense clamps down to receivers—a double headwind for his receiving volume. He needs two receptions to cash the Over, but his limited role and the stingy secondary suggest he'll stay at one catch or fewer. The Under at 1.5 cashes on zero or one reception, which fits his low target share and the defensive matchup.

Marks is a complementary back with just 2.3 targets per game and 8.7 yards per catch—a low ceiling for explosive plays. Buffalo's pass defense clamps down to receivers, and Marks' limited role means fewer opportunities to break free. The Under at 7.5 cashes on anything 7 yards or less, which aligns with his modest per-catch average and reduced target volume in a neutral script.
