Don't know if he beats out X; Covey has fumbled a lot on punt returns. I could also see one of the UDFA receivers (Edwards, Presley, Williams), or Schrader (if you want surehandedness without much wiggle, like with Kupp, Schrader's an option on punts. He's already an option on kickoffs, and they clearly liked him enough to poach him from the 69ers after cutdowns.) being used there.
We'll certainly get a spirited competition there. May the best man for the job win.
