Just for the sake of argument, if Gally plays no NHL games in 13/14, he could still be sent down to juniors and have the contract slide another year. There are also other games played limits that handle whether or not a contract year counts against future free agent eligibility and whatnot, but that 10 game limit is what you want to concentrate on right now. That's why you often see players being talked about as "he'll get a 9 game tryout and then get sent back to junior".
