What I think:
Casey is trying to win as many games as possible. Casey has weird ideas about "The League" and he has talked about it before. That the veterans deserve their due for staying in the league, being professional, doing their job in practice, etc.
Casey is going to continue to play the vets to bring up their value to trade them. Derrick Rose and Ellington are good players on cheap contracts that make sense for contenders. Mid-March is the trade deadline and I think they will be "showcased" until then.
I personally think this is stupid and Bey, Stewart, Saben Lee have already shown enough they need to play every game, 20 minutes at least.
I like Delon Wright and he played some huge games last year for the Mavericks. His job is walk the ball up the court and pass it to Blake Griffin. Below are some highlights where Delon Wright played like an all-star from a few years ago. He could possibly play like this but he is terrified of doing anything other than walking up the court to pass to Blake, because that is the system Casey has installed. If you dont walk up to court and pass to Blake, you sit on the bench.
Casey has a system that is terrible, he plays vets because they are due and probably are being showcased.
Blake should be cut, he is that bad right now.
In the system that makes the Pistons PG walk up the court and pass to Blake, Svi should have that job because its possible he could shoot lights out some games.
The team should look like something below.
Svi - Saben Lee
Josh Jackson - Wright(limited minutes)
Bey - Sekou
Grant - Sekou
Stewart - G-league guy
