Video: The Perfect Zero RB Team Is Out There (Best Ball)
I'm about to give us weekly ceiling the likes of which you have never seen before. I'm going to take one Mr. Keaton wanted poster missile. Going to add him in. He is on 25% of my teams on underdog up until this point. I'm very happy with that.

STACKED’s take

Positive signalValue

On 25% of Mattek's teams; signature ceiling pick for weekly upside.

Keaton Mitchell is on 25% of Davis Mattek's best ball teams on Underdog and is being selected to provide weekly ceiling upside. Mattek emphasizes this is a signature pick for his channel and expresses high confidence in the selection. Mitchell is referenced as a potential breakout scenario (scoring a couple long touchdowns in the right week) that could swing the zero-RB team's weekly projections favorably, indicating Mitchell is a lottery-ticket upside play.
