Yes, as is common knowledge the Edmonton Oilers will leave for Germany September 29th and not come back till after their home opener on October 6 against the Devils. This creates an exciting training camp dynamic as the roster has must be as close to finalized as possible before they leave to Europe.
There is an interesting number of players who are on the cusp of NHL action who could conceivably make the team out of camp. Much more so than Oilers teams of the past where rookies got force fed NHL minutes, regardless of how ready they were.
