Keon's offense hasn't translated, but the big difference is he stays out of the way and keeps our offensive flow moving. Davion is a ball-stopper when he's got primary ball-handler duty.
And flat out, Keon's defense has been better these last 3 games than Davion's all season. So if we're going with the no offense/all defense, the answer has to be Keon right. Far more versatile too with his switchability to defend multiple positions and play down a spot if needed.
Davion also has a skill that Keon doesn't have and that's elite ball handling and an elite first step.
Davion was doing fine hitting set shots too which I guess we need a bigger sample size for Keon.
So I wouldn't call offense a wash at least in terms of potential but I might be wrong.
On defense we have a large sample size on Davion and although I think Keon has been great, I don't think it's fair to write off a guy who everyone knows is a stud on defense.
If Klay Thompson hadn't hit that shot over him I doubt people would be talking all that much about players just shooting right over him.
Just saying that I don't think Keon is better than Davion, if anything they're equal right now therefore I don't think leaving Davion completely out of the rotation for Ellis would be fair.
