You can watch all the games on league pass. You might be able to find some full game replays on YouTube.
He mostly played in garbage time, where I'm very lenient in my analysis. It wasn't like he was just missing shots though, he looked like he didn't know where he was supposed to be on the court. It was even more obvious as a 3&D guy.
He had a few games where he got actual rotation minutes and he looked just as bad and lost as he did in garbage time.
I didn't watch him in the GLeague, but from what I understand he didn't do anything there to show he was an NBA player at first. Only Hardy saw him in practice, where he decided he wasn't ready.
What evidence is there that he was ready to play. How can people possibly say they saw something that Hardy didn't? It's just an annoying argument.
