It's different reasons for the two of them, Westbrook just lacks defensive awareness. I think people expected more from Mitchell because he's really quick and for his height he has good length and strength.

Undisciplined

I think Allen already had one of his best seasons last season, but he's continuing that trend, which is good to see.

I don't know. I felt Westbrook has better defense than Mitchell due to his athleticism and style of play (high energy, playing hard), especially during his earlier years in Westbrook's career. I had always seen Mitchell as a scoring machine and don't really mind him not being an elite defender.

Cavs still undefeated on a historic 9-0 run and still counting

I don't know if there's anything to this, but I thought Allen looked a bit leaner this season and he seems to be playing with more energy than last season.

Mitchell always profiled as a plus defender, but like Russ he never really developed it.
