Koerner labeled Corey Kiner his favorite undrafted dart throw. The rookie from Cincinnati has landed in the 49ers backfield, a unit that routinely turns obscure runners into fantasy gold. With Christian McCaffrey’s injury history and “Garando” already banged up, Koerner believes Kiner has a realistic path to replicate Jordan Mason’s surprise breakout and become a late-season league winner at essentially no cost.

Sam Monson cautioned not to overlook undrafted free agent Corey Kiner, noting that San Francisco’s backfield history (Mostert, Mitchell, Mason) shows UDFAs often beat out drafted backs. While Kiner’s measurables disappointed, Monson said his Cincinnati tape "is excellent" with decisive cuts and contact balance tailor-made for Shanahan’s run game. Monson wouldn’t be surprised if Kiner ultimately makes more noise than fifth-rounder Jordan James, making him a zero-cost speculative add in large season-long or best-ball formats.
