Love this for STL. It's a no risk situation, Kap comes in and performs decently or even possibly performs better than expected, the Blues have a good player at a fair cap hit for next year that they aquired for free but can flip for assets at the TDL next year if they aren't contenders. Kap comes in and becomes the worse player in the league, you got him for free and he only costs you money/3.2 in cap space for one year only so you let him walk after next season is over.
Blues can't lose in this situation.
