I'm very cautiously optimistic about Mason this season, mostly because I picked him up cheap last summer in my league so I'm hoping he can pick it up a bit. I've read that he's taking this year a little more seriously and with a legit goalie sharing the crease in Columbus maybe Mason realizes it's time to pick his game up before he Jim Carrey's out of the NHL.
To actually answer your question, I think he might be a safe play tonight against Phoenix but I wouldn't go out of my way to grab him and start him. If he's on your roster, and you need a goalie start go for it but I wouldn't go streaming for him.
