Jason Marshall has gone from marginal back-up to starting nickel in the last 10 days. He typically plays outside slot but has adjusted well to being on the inside. Being a 4 year starter in the SEC looks pretty good on any resume
Inside nickel covering the slot should suit his skill-set a lot better, and while it's horrible that Kohou is out for the season, it's opened this opportunity up and he's making the most of it.
Hopefully he continues this trajectory and proves my early predictions wrong. If he does well enough, Kohou could find himself playing outside a lot more when he does return.
