Morrissey isn't affected by the 9 game trial anymore. That applies only to junior players.
Harrison is not slightly more valuable than Pardy. The best thing that could happen would be if he was claimed off waivers.
Exactly. If that were the worst case scenario then it is manageable. Pardy will clear waivers, he has before and will continue to. Unless a team is in a pinch and claims, in which case he was a very serviceable D man while here.
Either way it is low risk in sending them down.
