They all get more than one game to prove they belong, but if they don’t I doubt Danny would hesitate cutting a guy with a contract and giving it to someone else.
As far as cutting Strus or Semi, I have seen mention of cutting a 2-way player would set a bad example to agents of other 2-way players and they wouldn’t sign here. Those guys don’t have much choice. They are barely scraping at the NBA door. There are dozens of other players in the same boat to choose from if one guy says “no.”
For Semi, well, lots of draft picks get 3 years to prove themselves worthy of a spot, but Red cut Michael Young, a 1st round pick, before the season even started, because he was too much of a project to contribute on a contender and Red didn’t want to give him 2-3 years to develop.
If anything it would send a message that it doesn’t matter if you have a contract, you have to be 1 out of 15 when the season starts or someone else takes your place. If Max doesn’t make an impact soon, then maybe he’s Javonte in a few years trying to make the league again at 26, or he’s an assistant coach at DePaul.
