Well, the flipside is that he could be put in a position to fail miserably if given too big of a role and thus be set back even more. I've watched most every game of his and IMO, he's not ready for a bigger role yet.
That said, I think they could swizzle the lines to give him a bit better linemates though, but there aren't a ton of options when the Canes essentially have 2 4th lines. When Rask comes back, that should change though. It's a catch 22 as he (Svech) isn't ready for top 6 ice time, and the Canes don't have enough good players in their bottom 6.
When Rask is back, I'd go with:
Ferland-Aho-TT
McGinn-Staal-Williams
Foegele-Rask-Svech
Or, better yet if the trade for Nylander
Foegele-Nylander-Svech.
