Micah Kiser

Any opinions about Micah Kiser performance last night? Should we be worried about his lack of speed. Seemed like he was tackling from behind most of the night. Can we contain a guy like Kyler Murray with Kiser at LB. Littleton had speed and helped contain Murray last year when they played them. I'm thinking they are going to need a safety like Burgess or Rapp to spy Murray when they play him.
