I'm not saying he can't be the long-term back-up. I'm just saying that Mason isn't a sure thing yet, and the Flyers need to have solid back-up again next year just in case. Heeter might be the guy in another year or two.
He's going to be 26 next season tho. If he doesn't get his chance now there might not be much of a future.
