Yeah, Beasley-Cade-Thompson-Harris-Duren/Stewart should be the starting lineup.
I understand the stigma about not starting. But Ivey would still get 30+ minutes a night. I doubt his stats take a hit at all, and maybe go up since he is playing against bench guys.
To me, this is more about Beasley than Ivey. If Beasley isn't around I would have no problem starting Ivey.
I wonder if they wait on making a change until after the trade deadline.
