Davis Mattek called Caleb Johnson the slam-dunk Round-7 hammer for best-ball drafters still hunting an RB2. The 220-pound Iowa product out-gained the entire Hawkeye passing game in 2024 and still finished second in the FBS with 861 breakaway rushing yards despite a disappointing forty time. Mattek thinks the fit in Pittsburgh is perfect: Arthur Smith’s offense will almost certainly rank 32nd in PROE, Mike Tomlin loves reliable grinders, and the only real competition is 208-pound change-of-pace back Jaylen Warren. With quarterback play likely shaky (Will Howard, Mason Rudolph or a Hail-Mary Rodgers trade), Smith will lean on the run, creating a plausible scenario where Johnson sees 25-plus December carries and spikes in the fantasy playoffs. Mattek compared him to ‘Brian Robinson with juice’ and believes his combination of bell-cow build, breakaway ability, and seventh-round ADP makes him a potential league-winner before summer ADP catches up.
