Chuba Hubbard has a 0% probability of a legendary upside season. I think a really, really good season for Chuba Hubbard would be like 14 and 1/2 points per game. But, his probability of not playing very well, his probability of being the number two running back on his team, his probability of not contributing in the pass game is actually quite high.

STACKED’s take

0% legendary upside; 14.5 PPG ceiling; likely RB2 with no pass game.

Davis Mattek assigns Chuba Hubbard a 0% probability of a legendary upside season. A really good season for Hubbard would be approximately 14.5 points per game. Mattek emphasizes that Hubbard has a high probability of being the number two running back on his team and not contributing in the pass game, making him unsuitable as a building block style player due to his limited ceiling and downside risk.
