Like Terrance Jones, Nick Richards, and Oscar. Who came back and sat their second year that was good enough to play?No, the players can't be patient anymore because of the culture. Cal created that culture of "if you're not leaving year 1, you're sitting year 2" so the kids bump on our of year at any chance. At other schools it's not nearly the problem.
Also, Bradshaw doesn't have a motor. Jumping around on the sidelines or getting animated at a call you disagree with is not a motor. Nor does he embrace the physicality of the sport.
When's the last time he attempted to set a screen? When's the last time he really bodied up against someone under the basket? When's the last time he tried to tear down the rim on a putback? He can try those things, he just doesn't want to.
Don't even think about blaming this on the "fans not being patient".
