Kuhn could be a decision at cut-down time, but I'd expect him to be kept for his reliability in blitz pick-up to keep the franchise from getting crushed if/when needed to do so. Rip and/or Lacy (who's probably a full-fledged three-down back now) may also prove reliable in that fashion but Rip will need time to learn and Lacy could get hurt at any time so Kuhn's more of a security blanket than anything.
