So today Richardson was sent down to Lake Erie, and TJ Hensik was called up to play for the Avs (Guess who will be at his first game :) )

What I want to know is why isn't Wyatt Smith being sent down instead. I have a feeling it has more to do with contract status than anything. I don't know anything about the differences between a one-way contract or who can be sent down on what types of contracts. I would imagine it's more difficutl to send a guy like Smith down than it is Richardson. Richardson, of course, just had a rehab stint with Lake Erie so maybe this send down is more indicitive of logistics and contracts than anything else. Anyone out there know how sending a player down works (Maybe Jori?)
